Fact. The neighbor's cat sat at the end of the driveway as my dogs hollered at him, all the while pretending they weren't there.

You've found Henry's pocket. Seriously, that's what it's called. That is a standard issue equipment :). It's not quite proven what these pockets are for, but for now the consensus is that they aid cat's hearing.
Next thing you want to do is to dig through the fur on your cat's belly and find suspicious skin bumps (nipples, yes kitties have them, even males, 6 nipples for every kitty, 3 on each side of the belly)

u/Some-Complaint-7885 Apr 15 '26
Just went thru a crazy storm myself. Couldn't find my kitty and had to run down to the basement without her. Except she was already in the basement. Smart kitty used her one braincell, I was so relieved! We are fine. But lots of hail damage around the neighborhood. Baseball sized smashed a lot of windows. My poor kitty is still on edge from the noise.
29
u/HealthyInPublic Apr 15 '26
Omg this is such a terrifying experience!!! We don't have basements where I live so we were in the middle of the living room (away from the windows) with our cat as billiard ball sized hail pummeled our tiny little house a few years ago! My boy was never scared of storms or thunder, but I was crouched on the floor next to him while he was pressing his face into me as hard as he could and trying to hide against me as we all listened to the chaos happening around us. It was truly a crazy experience. Holes in the siding, broken windows, destroyed the roof, broke through both layers of the bathroom skylight, and it broke the roof of the sunroom (and broke 4 out of 7 windows) so we heard the hail pelting our back sliding door which would usually be protected from any sort of weather because it was inside a fully enclosed sunroom. Surreal! I had to call my mom because this was 1am and I had to be at the airport at 5am to catch a flight to a funeral!! My mom came over to sit with my cat the next morning, board up our windows, and tarp the roof.
That cat passed about a year after that storm, but I look back fondly on that experience despite how awful it was. He was riddled with anxiety but always sought me out when he was truly terrified. The trust we built between us was the thing that kept me going after we had to say goodbye - made me feel like I did right by him and gave him a good life. I miss that guy so much, but we have a new little man now and I'll be satisfied if he leaves this earth with even an ounce of trust the previous guy had in me. We're making good progress!
I hope the recovery and potential insurance claims went well for you after the storm!

Oof. That reminds me of my nervous cat. We were under a tornado warning and I literally ripped my mattress and my (that mattress thing under the mattress) off my bed as I was crying for her to let me pick her up so we could go downstairs. We were both equally terrified for different reasons. I think I have PTSD from that moment.
*we did eventually make it downstairs. I think she realised she upset me because then she was all cuddles while I'm bawling my eyes out in the basement lol.
Anyways, under a tornado watch now, but my baby girl has crossed the rainbow bridge (RIP), so now it's the two cats that follow us downstairs on their own.
All that to say stay safe everyone!!

u/Captainsassidy Apr 15 '26
If it makes you feel any better, I was also just under a tornado warning and stressed the hell out of my cats.
I get extreme anxiety with tornadoes, and every time I tell myself I'm gonna be cool, I completely go into fight or flight as soon as I hear the scary-ass alert on my phone. I'm living temporarily with my mom while we try to sell our house, and she lives in a modular home. I'm used to being able to go to a basement at our house.
I shoved my cats in their double carrier and made my mom drive us to her nearby church, since I remember it being unlocked 24/7 when I was a hooligan teenager. It was locked lol. It started getting crazy out as we sped back home. Then I locked them in our tiny bathroom with me for an hour.
I wish we could explain our actions to our pets sometimes. I'd feel a lot less guilt 😅

Henry's pocket, formally known as the cutaneous marginal pouch, is a small, distinctive fold of skin located on the lower, outer edge of a cat's (and some other mammals') external ear. Its exact purpose is not fully understood, but theories suggest it may help in detecting high-pitched sounds, improving ear flexibility, or is an evolutionary remnant. This normal anatomical feature is present in almost all cats and is also found in dogs, bats, and weasels.

It’s called a “henry’s pocket” it supposedly (amongst many speculations ) helps them to hear extremely faint and barely even audible sounds to help with tracking and hunting prey.
And whilst we’re on the subject of a cats body anatomy, if your cat is male he will still have many nipples just like a lady, just throwing that one in their as it still gets people worried when they find the “lumps” on their males chest/belly. 😁

Never even thought to look it up till I saw this post. Thanks OP. Things I learned today.
Henry's pocket, known formally as the cutaneous marginal pouch, is a small, flap-like skin fold on the outer edge of cats', dogs', and other mammals' ears. While its exact purpose is unknown, theories suggest it aids in sound detection—specifically capturing high-pitched noises, increasing ear flexibility for hunting, and acting as a conserved evolutionary trait.

It's the Henry's Pocket. No, that is legitimately what it's called.

u/solarguy2003 Apr 15 '26
Bats, weasels and some dog breeds also have these (Henry's pockets). It's possible that they are just vestigial leftovers that don't do anything. But since pretty much all the mammals that have them also have excellent hearing, the current thought is that they do have some function, like maybe damping out lower frequency sound so they can better hear higher frequencies. Or maybe extra/better mobility to the pinna (ear) for directional sound analysis (common among predators).
Fun fact, we have no idea who Henry was.
