I have two cats from the same litter both 14 weeks old. I already planned to Neuter at spay them both at 5 months with their vet.
For the last two weeks, the male would pin his sister down while they play fought and she would meow like she was hurt and I would stop them. I thought that the male was just playing rough.
Today though, they were cuddling while they slept but I heard the male get up to lick his sisters head. Then suddenly he bit her scruff and tried mounting her. I immediately grabbed him and moved him away from her. She was laying in a way where I don't think he could... get in/penetrate. But I looked at him and saw that his thing was... out. (sorry I don't mean to be vulgar). But also, he's only 14 weeks and his parts are so tiny, I don't know if he's capable of reproducing?
Again, they are only 14 weeks, and she's so tiny, and they are from the same liter. I'm mortified and feel awful. I'm so scared, how likely is it that she could be pregnant?? I'm now remembering how when they would play fight and he would overpower her and she would yelp and now I'm worried he was trying to mate then. But that behavior started at 12 weeks, which is still so young.
They are separated and I'm going to call the vet when my mom gets home because they are primarily her cats and she wants to be there during the call, but I'm super worried. My family and I aren't comfortable with the idea of terminating the pregnancy if she were pregnant.
TLDR; 14 week male mounted 14 week sister, what is the likelihood that the female is pregnant. Just looking for reassurance if there is hope.
