My male cat just bought a dead kitten TWICE?

Male cats don't always recognize kittens as connected to them in any way--they don't all seem to remember their siblings as kittens. They just see kittens as small food sources like squirrels and mice and baby rabbits. If your male cat isn't neutered, he also will want to kill the kittens of any female he may want to mate with. That's what the male big cats do, kill the kits so they can mate with the mother. Losing kittens seems to bring a female back into heat real fast. If the mother cat isn't willing to fight off a male to defend her kittens and possibly getting seriously hurt or even killed herself, the male may kill her kits.

He's doing it because he sees the kittens as competition and if he kills them, the mother cat will go into heat again and mate with him. This sort of behavior in male animals is very common in nature. The way to fix it for yourself is to get him neutered. Once he's neutered, his sex drive will be gone and he will have no interest in female cats. I'm sorry you've had to see this. I know it's horrifying.

It is very important to keep male cats away from new kittens. The male will kill the kittens. I don't know why.

Male cats do kill kittens, it's important to keep them away from kittens (particularly new-borns), this isn't specific to your cat, all cat will do this, it's just in their nature. Also if the kitten's mother is in heat, he will kill the kittens and then try and mate with her again.

are these your cats kittens he is killing? male cats will kill the females babies so she will go back into heat . if she has no babies she will go back into season, thus enabling him to breed with her and ensure his own genes are carried on.. nature is a scary thing, maybe get your male cat neutered so he wont feel the need to want to breed ?

It is as Ken said. Your cat is instinctively killing the offspring of his competition so the female will go back into heat and he has a chance to impregnate her and propagate his own genes.

Please get your cat neutered.

Once he is neutered he will no longer have the urge to kill kittens.

Very sad.

Male cats will kill kittens. It is important to spay pets (both male and female), so they don't have unwanted babies.

Its prey to him. Maybe the mother got hurt or killed and the kittens are looked at as prey (like a rat/squirrel). I would advise you to keep the cat inside and have him neutered. Tom cats are more likely to be killing kittens then neutered cats.

Seriously? You gave your cat money to buy a kitten twice? everyone knows cats are terrible with money.

That happens in nature The male will kill the kittens so the female will go into heat faster so he can mate with her.
