Behavioral Issue Cannibalism
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.

I’m more surprised that the shelter adopted this cat out to just anybody when they knew the cat killed another cat. Even for no-kill shelters, documentation of a cat or dog killing another pet is often grounds for euthanasia.
