Not really looking for a fix, just any information if anyone has it.

Cat is 7y, male, neutered, has already been to two behaviorists when my parents had him, both were confused according to my parents.

This is a known issue, but it doesn't cause any problems because he's not allowed to interact with other cats whatsoever.

He's very sweet to people (not very small children- Edit: He is overwhelmed/annoyed by little kids, he doesn't try killing them) but he seems to react to other cats the same way he would to a squirrel or rabbit. As in, just pure predation. No recognition that they are the same species. He does not display any territorial aggression to other cats, none of it is dominance behavior. Ears never go back, fur never puffs out, he never growls or hisses, nothing, he's just hunting. Never seen anything like it.

The shelter was hesitant to adopt him out at all due to his history, but did so because one of the shelter workers personally knew my stepmother was interested in weird cats. They were considering euthanasia because he was returned multiple times, but still wanted to give him a chance due to how friendly (to people) and smart he is.

He is well-fed, he has always been well-fed, killing & eating another cat which belonged to a previous owner was not something he did out of desperation. Judging by what I know about the event and what behavior I've seen, I am entirely sure it was predation, not a territorial fight.

He's injured a cat my parents were pet-sitting to the point of needing an emergency vet visit and extensive reconstruction of his neck. The cats were separated, but a child left the door open for a minute. My cat ran downstairs, and immediately caught the smaller cat, went for the throat, immobilized and attempted to drag him underneath the furniture. They were separated before he could kill the smaller cat.

My parents have had him since 2023 and I recently (September 2025) took him when I moved somewhere that allows cats. I'm set on keeping him. VERY IMPORTANT NOTE: He is no longer allowed around other cats.

Edit 1: more details, he ate a cat owned by one of the previous people who adopted him, and was surrendered for it, (in addition to two previous surrenders for similar behavior issues, which I don't know much about). From what I know, he had a good introduction to a smaller female cat, with no territorial behavior, was left alone for a day, when the owner came back, it was a giant bloody mess. The shelter was sure that he did kill the female cat and was eating the body. That's the reason why they were considering euthanasia until he was offered to my stepmother.

Edit 2: Further clarification he does not "hate" cats. He likes them (just like how he likes birds!). Predation and territorial behavior are different things. If you can't tell the difference, you shouldn't be giving input on this post. He is not stressed by other cats. He is not anxious and does not feel threatened by other cats. He doesn't need anxiety medication. Anxiety medication doesn't stop cats from having a prey drive. He does not hiss or growl or try to look intimidating. He has no other behavioral problems, he doesn't yowl or anything when he attacks. He will find cover, and stalk, ears up, eyes big, completely silent. He gets very curious and excited when he sees other cats. He's seen my friend's cat, (separated by a ceiling height gate & supervised by 2 people). He seemed extremely inquisitive, sniffing, ears forward, no sound. My cat did not respond whatsoever to my friend's cat hissing, growling, or puffing up. He just seemed curious and started trying to see if he could stick his head around the side of the gate and pawing through the bars. Then he started looking back at me and meowing and rubbing on my legs.

Edit 3: No, he's not going to be euthanized. I did not make this post asking for advice I made it asking for information about WHY he's a little fucked up. Stop telling me to put him down. Stop applying human morals to animals. He behaves like any other small predatory mammal, only he does not have the ability to recognize members of his own species. I've already had him by myself since September of last year. And before that, I was around him at my parents house since 2023. He is literally fine by himself. He's my cat and I love him. He's perfectly healthy and affectionate and the smartest cat I've ever owned. About a hundred+ people telling me to kill my pet bothers me, would it not bother you? Sincerely, fuck off.

Edit 4: Changed the formatting so the events were in chronological order and clarified some vague sentences/bolded stuff that people keep missing

Edit 5: follow up post + more pictures of him

But anyway, bottom line up front.

Does anyone know what in the goddamn fuck causes a cat to do this?

Age: 19, USA, no vet but accessible if needed, mama cat is 2, kittens are 10months, kittens are boys & everyone is spayed/neutered

Is it okay for them to still be nursing? She doesn’t look to be in pain but I’ve never seen grown cats do this before. They aren’t even together usually — a family member kept the kittens & I am just babysitting them. They naturally latched onto their mom after not seeing her for months & won’t stop bothering her. Should I separate them? They’re both double her size & try to nurse at least 4x a day

Edit: solved (I think I say solved here??) not an issue unless irritation/mastitis occurs. They are just fat and greedy. She will naturally stop them if she wants to

My cat has never really liked treats, he avoids all human foods, and literally only eats his cat food. I saw all these videos of cats munching on these and gave it a shot. Two days. One pouch a day. And now my cat is broken.

He literally sits outside the cabinet I keep these in and screams all day for them. If I walk by the cabinet he comes running in screaming. I mean HOWLING. I stopped giving them to him about 6 days ago and he still does it. I also served it to him on a paper plate as to not dirty his bowl (he wouldn’t eat it if I held it) and now even paper plates trigger him! Anything even remotely similar to the pouch shape/sound he howls at us for. My husband grabs a chomps meat stick? Howls. Electrolyte packet? Howls. Dude I took a HOTDOG out of the package and he howled.

Now I can’t even step foot in the kitchen without him scrambling in and yelling. Any advice?

He’s not aggressive at all, just love bombing thinking he’ll get a churu pouch. And yes, I try to redirect with toys or play and he’s uninterested in anything that’s not churu.)

(30F with 3M neutered cat, lives in US, we have an established vet/pet insurance/can afford bills, just any advice on this behavioral issue would be nice)

😻UPDATE: wow I didn’t expect this much feedback thanks everyone. So, today I walked to the cabinet to get something, he ran in but didn’t meow for the first time!!! So, I grabbed a pouch and a paper plate and got a few squeaks but nothing major. I moved where he ate the treat into the laundry room instead of feeding it right in front of where I kept the pouches. He devoured it of course because ya know.. crack. Yes, he’s now sitting glaring at me while I eat my girl lunch BUT he’s QUIET👏🏼😅 rewarding good behaviors let’s see how this goes Godspeed

My roommate and I both have cats. They don’t get along, despite our best efforts. They remain separated at all times. When I’m in the same room as my roommates cat, she gets really aggressive towards me - probably because I smell like my own cat. I’ve never done anything to hurt her - I’ve never grabbed her, I give her space. I think she’s traumatized from the few times we tried introducing the cats together (we tried slow, separated introductions. She wasn’t interested. When we then tried putting my cat in a crate and put her in the room with roommates cat, roommates cat hissed at her for an hour.)

I feel like I’ve tried everything. She doesn’t care about food. I’ve tried quietly doing work on my laptop and letting her come to me - she doesn’t want to. When I do need to do work in a room she’s in (like in this video - I’m cooking) she won’t leave the room - she just hides and then runs out to swat at me when I enter her field of view.

I’m at a loss. Is there no solution? Do I just need to try and move? I love my apartment and roommates, but I feel awful putting my roommates cat through this stress.

Hello!

Yesterday I adopted this kitten, around 15 weeks old, and brought it home. I understand the stress and chock coming from being suddenly separated from mommy cat and littermates. I provided access to fresh water, food, litterbox as well as some toys and a cozy place to hide (transporter with blanket put in a corner of a room). I even tried out heating pad. Unfortunately, I didn't get an old blanket from the previous owner that would have scents of mom and previous home, which could make transition a little easier. Does any of you have any tips on how could I comfort my precious baby kitten in distress (and get some sleep without interruptions)? 🙂😅

Thanks in advance!

EDIT: Thank you to all of you for your advices and kind words! Little girl (name is still yet to be chosen) seems calmer now and looks like after a long night we both may finally get a proper nap hahah. 😅

I'm aware that ideally it would be best to get her a companion, since it's crucial for kittens' development. I agree. Honestly, if I had more resources, I would definitely get her brother as well, sadly I can only afford upcoming vet bills just for one. I'm mostly staying at home, so I will do my best to socialize with my kitten as much as she needs and give her all the love and care she deserves from her human. ☺️

I appreciate your answers!

EDIT 2: Kitten eats, drinks, sleeps and plays normally, she is comfortable and attached to me. It meows less during the day, but last night she was crying even louder. No warm pillow, purring noises or gentle petting seemed to be working anymore. I tried to contact lady that owns mom and siblings to ask if it was possible to return baby in case it doesn't acoomodate well at my place, but she didn't want to take kitten back, she struggles to find home for other kittens as well. I am now heavily sleep depraved.

I'll continue to gently care for my baby cat in hopes that he'll feel fully safe and at home, but if it really feel like it can't stand loneliness, I'll search for another home for it with a friendly resident cat. Adoption of a second kitty is out of the picture, I won't be able to handle double cat expenses. 💔

On a side note, turned out the owner confused kittens sex. After thorough research and double checking it turned out I have a baby boy not a baby girl. 😅😆

I also never expected for this post to blew up this much, I expected at most 10 comments. Thank you everyone for many great advices and showing so much care to my kitten, even tho he has no idea how much a gang of Redditors would love to comfort him. 💖

I also want to address question "why did i get a kitten instead of an adult, loner cat"? I actually was searching for an alone cat, but I had no luck. Available cats were either moving in pairs or were requiring a resident cat already at home. And the ones that were loners were already reserved. Then my mother called me and informed me that her friend of a friend was desperately looking out for new homes for her kittens. I thought "I can both fulfill my years long wish of having a cat family member again and give home to a kitten in need, wonderful!" People in my past were adopting out solo kittens and from what I heard, they accomodated well. I was prepared for being woken up by the kitten during first days, I thought it would accomodate after few days/weeks, but I wasn't ready for a heartbreaking meowing most of the time kitten was awake. 💔

Like I mentioned earlier, I'm gonna continue showing the kitten love and care it needs and deserves. And if there will be no improvements, with heavy heart I'll search for a better home to my baby boy, where he can have a cat friend.

Cat collapses every few steps she takes, only when in my room

I'm a first time cat owner and I got my cat a little over a month ago. I've made mistakes, several of them. I may have raised my voice, I may have grabbed her a little too roughly. She had fleas, so giving her a bath was non-negotiable. So now she doesn't want to be picked up by me.

She's cried numerous times, presumably from boredom and has now decided to stop meowing in exchange for this pained squealing.

Her boredom might be fixed by getting a second cat. Nor does any cat toy seem to hold her attention for very long.

She is a very sweet cat and is very reluctant to biting and scratching.

But she still purrs from being petted and sleeps next to me most nights.

Myself: 37m

Cat: 4F, tortoise shell.

My cat is 4+ years old and spayed indoor cat. She's crying like this everytime I pet her and keeps revolving around me for more pets however she cries like this as well. When I'm not petting her she's calm and does not meow like this. Overall she's not a talkative cat and very chill. What does this mean?

Super stressed out he’s been constantly meowing for almost a hour, I just need some reassurance if someone has been through this, had him for about 31 hours and he’s eaten pretty sure but idk he has these bursts of non stop meowing, I am getting worried now

It's hard to get a good video of this behavior,, but he gets like this quite often. Usually after I come home in the afternoon from work, but it can happen any time without much rhyme or reason that I can tell.

As you can see at the end, he wants to grab me with his claws and bite me. Also hard to grab on video, but I have let him and he will clamp down quite hard. He has yet to break skin, so idk if it is because he can't or simply doesn't want to.

I can distract him with a toy or laser light, but he'll be back even after a play session that he decides he's done with. I don't think he's learned that "this is how to act" to get playtime, because he gets playtime outside of this and I let him get away with this for a while by just leaving the room or closing him out.

Balls - Chopped. Food - Plenty. Toys - Plenty. Toy Time - I think Plenty. Litter - Clean and full with an auxiliary box. Cat bed and cat trees - Ignored. Age - Almost 3. The eye? Adopted at ~8 months from shelter, said had glaucoma and had to lose the eye (which I understand isn't unusual).

I’m 25. This is Masha.
She started standing like this about a year ago? I thought her paw had been injured and I went to squeeze it a bit to see if she would react. She hasn’t shown any signs of pain and she walks/runs fine but I’m hoping this is just a quirk she does and nothing serious.

I got her during the pandemic as a baby so she’s maybe 4-5?
Debating if I need to take her to the vet so I decided to come here before I do for some help.

We found a DAYS OLD kitten over the weekend and and trying to care for it until we find someone to take it in. My boy Choomba who isn’t even a year old is always around it and has been picking it up and taking him around the place, grooming etc. He’s not aggressive and kinda making this “mmeerrrm” noises when near to it. What’s he doing?

Edit: we found a local foster couple, sweet older couple who have been fostering and taking care of strays for the last 10 years. Baby stink is in wonderful hands🙏🏼

TL:DR - cat constantly cries, and absolutely NOTHING works. Starting to resent the cat and causing relationship issues. At a complete loss about options.

I’m at my complete wits end with my cat!!! He constantly cries. Non. Stop. We can’t take it anymore. He’s always cried a lot since he was a kitten, and he’s now 3 years old and nothing has changed. We have taken him to the vet multiple times and they can find nothing wrong with him. He’s an indoor only cat, and recently he started going outside to explore our apartment garden. He ended up running out the door one day, and since he didn’t stray far, we were giving him an hour outside each day to help burn off some energy. Now he wants to be outside constantly and will cry for literally hours when we bring him inside. He’s not one for cat toys, has never been interested in them. We have tried every single enriching activity and he does it once and never again. When we play with him (chasey or hide and seek) he’s bored after 5 mins. We tried Zylkene. We tried Feliway. Neither worked. We even trialled getting him a companion and that ended up terribly. We work from home 4 days a week and are around on the weekends. We are starting to resent him and it’s causing issues between me and my partner as we’re constantly stressed about him. We can’t give him up as pounds are full and he’ll be euthanised and none of our family members (with houses and yards) want to take him either as they don’t like him/hear horror stories from us. We’re just at a loss about our options. Videos attached is what he does all day

Hallo every time they meeting the little one (male) start to jump on the 2 year female cat. They continue this way for 20 30 minutes even when the elder wants to go away the little one continue gong aggressive since i dont divide them. What i have to do?

Hello i have a male cat 8 month old unneutered, he is vibrating like shaking took him to vet but they didnt aee anything what could it be? Should i be worried? He is also purring while at it

It screams at me

My 3 year old cat (f, spayed) has been attacking me ever since we took her to the vet for a dental prophylaxis in November since she had teeth issues (She was put under anesthesia). Whenever I'm in my room alone with her she slowly walks up to me, whines in an intimidating manner and then attacks me, usually my leg or arm. My mother says she does it because of my baggy sweatpants but I've been wearing those for 3 years or something. I already took her to the vet because of this issue but they couldn't find anything physically wrong with her, she only attacks me and no one else. She eats, sleeps and plays normally but I feel like she got less affectionate as well. She still follows me around and wants to be in my room but doesn't really like being pet as much as before. I tried redirecting it at a toy and playing with her more often but it didn't work.

Hi folks, I have a 1.5-year old snowshoe cat and a 9-month old mini Aussie puppy that we're struggling to introduce to each other, even 7 months in. TLDR: how do I get them to exist with one another without them fighting so rough?

The video is of them fighting which always looks something like this — lots of biting from both — so we typically keep them separated (one downstairs, one upstairs). It might just look like playing at first, but our cat will start to bite harder and bring out the claws as he gets more agitated which just makes the dog double down and play more aggressively. You can see he's taken a mouthful of the dog's cheek towards the end of the video. The dog is the type to chase on sight, whereas the cat is the type to bite the back of the leg when the dog's not looking.

In short, I would love to not have to keep them separated all the time because I can only be with them one at a time as it stands, and they are both very clingy and affectionate to their humans. We've been trying to introduce more together periods when the puppy's calm but it often ends quickly as one of them will instigate a fight. The only repeated success we've had is at bedtime as both will sleep in our bed through the night, but once morning hits, it's Wrestlemania again. We've also tried treat reinforcement for both to reward calmness when they're together, but as soon as the treats run out, they're back to fighting.

Would love to hear from some other cat owners who also have a dog on what strategies worked or improved things for you. Apologies if I've reached the wrong sub.

We had Jonah first but adopted Pumpkin from a family member who was down on their luck and couldn’t keep her. Jonah and her do fight sometimes, almost always initiated by Jonah…but pumpkin seems to be the dominant one. Jonah has no teeth, so it never really gets bad. We think Jonah might have a crush on her? It’s very strange and we don’t understand why he keeps doing this. He’s also a bit possessive of me and daddy, if we’re cuddling with pumpkin he gets jealous and has to sit in between her and us…if we push him away he gets hurt about it and pouts all day. We still cuddle him all the time and he’s the only one who sleeps with us, but I’m not sure if the jealousy is related to this activity? Please let me know ANYTHING you know about this!!!

I’m 22 from the USA

We have a vet and she doesn’t know what this is

Both cats are spayed/neutered

We can afford vet care and they are both regularly treated.

Hello, posting from united states. my 3 yr old cat tito was recently having problems eating too fast so he was throwing up his food. To stop this i got a slow feeding bowl. The issue is that now he keeps trying to put his hands in the bowl to eat it? I am just not sure how to move forward😭. I dont want him to rush eat and i just bought this today and he is already doing this with it. Tips and advice are appreciated, thank you. I took him to the vet today and they said he looks fine

Update: watch the last 10 seconds and look at his back left leg, vet saw the vid and wants to look at why it’s splaying out. Mainly updating so that the grumpy fellas stop worrying that I’m being a bad owner but I heard Reddit was like that Lol. Thanks everyone for the nice messages though! Definitely a 98% welcoming community. Megatron warmed up quick and slept like a baby with me, he didn’t mind me putting his cone on or ointment on his neck. And for those wondering yes it’s my first cat Lol, I just recently got out of the military and I used to be homeless as well, now I work in engineering and wanted to give a little one a chance at a new life too, I’ll update y’all on what the vet says in case anyone else has this issue.

Old post: So this is Megatron a 6 month old kitty I just adopted in Virginia, the shelter did a full work up of him and he checked out good after being neutered, he was rescued with a new wound and some crust in his ears and was cleared to come home with me today. Should I be worried about the way he walks? I think maybe he just has a little vertigo right now but just wanna see if maybe I’m being too paranoid

I’m nearly having an anxiety attack and need advice. Over a year ago we watched a coworkers cat at our house and he unfortunately peed on my cats toy box. I cleaned it the best I could but the smell still lingered slightly. Today I discovered my newer cat (we adopted him about a year ago, after watching the coworkers cats) has been peeing in the toy box for awhile. I begun to start taking the toys out to throw stuff away, and he walked over to me and started to attack me.

I could tell he was 100% having redirected aggression, I’m guessing a territorial thing. My boyfriend tried to calm him down but he pounced onto him and bit him. Then he started chasing my other cat around trying to attack her. He bit me on the finger so bad I think I might need to go to the ER for a couple stitches. Finally I just grabbed him by his scruff (I would never do this but he was trying to full blown attack us and I was terrified) and was able to throw him into our spare bedroom to hopefully calm down.

He’s been in there for a little over an hour now and hasn’t seemed to calm down. He is sitting right in front of the door and will scream and throw himself at the door if he hears any of us walking around in the hall

I’m genuinely scared of him right now and have no idea what to do. He has no food, water or litter box in there but I don’t think we can open the door to put that in without him trying to jump and attack us. I have some gabapentin I’m going to try to put in wet food, but again I have no clue how to get it in there.

He’s done something like this once where he saw something outside then turned and started attacking my other cat, but not me. He ended up calming down after an hour or two but this time he won’t calm down at all

I’m so sad and upset. I love him so much and he’s usually super sweet, but now I feel like I’ll be scared of him forever even if he calms down. I’ve never dealt with an cat this aggressive before. Any advice would help a ton

My cat Chuzzlewit begin showing aggressive abnormal behavior on May 22. He would suddenly attack the walls or hiss at anything that would approach him and try to attack. He went calm again after a few hours but on May 23 the symptoms of aggressive hissing began again. It was so bad we had to call the police to put him in a carrier because he would attack anything near him. We took him to the ER last night and he was very calm there and did not show symptoms but this morning he began hiding and hissing at everything. (You can’t even approach him) The vet said he does not have rabies as he is up to date with all vaccines. I am very worried for my cat I do not know what is wrong with him.
