...Damn the mental images!!!! I won't sleep today!

That must've been a terrible thing to see... Especially right after leaving to get stuff for them. I'm not the type to have "bad" dreams of any nature, but psychotic cannibal cat from hell may just cause a few awakenings...

That exact same thing happened to me, except it all started with one stray cat we decided to start feeding through kindness, who brought many kittens, who went through all this when they got older.

No point punishing the cat. She won't understand what she did that was wrong.

Guess that's how cats do abortions...

That's not something you're going to see every day.... Im sorry that happened, but at least I now know I have a morbid sense of humor because I found all of this amusing...

Welcome to CatBortions: where your cat can get an abortion before AND after giving birth.

Was the babies dead? Because I heard some animals eat the dead ones

No 216, they were still alive, even after they were eaten and puked back up.

Thank you for clarifying things, OP, I too went through that but they weren't even my cats, they were stray cats. After seeing the corpses on my driveway I had to clear my head and understand that that's their nature, they're not evil or full of human emotion they just are. Everyone seems to forget that cats are miniature predators, small lions, I bet they think of themselves as feral lions, kings of their territory. I love cats :)

I'm blown away that the mother of the kittens was just chillin cleaning herself.

if the mother had literally just given birth she wouldn't have the strength or will to protect the kittens. there is no bond there yet. it takes a day or two for the mom to recover enough, and start feeling the need, to defend her babies.

Sometimes animals will eat their young if there was something wrong with them. Maybe the kittens were somehow dysfunctional. That would explain why the mom was so chill about it. Then again, some cats are just evil and others are just bad parents...

I really doubt the mother cat was indifferent to the slaughter of her newborn kittens, she was probably too exhausted from giving birth to a litter of kittens to fight back. I can't help but find you a teeny bit irresponsible for not separating your other cat from the mother cat once you found out she had given birth. It can be dangerous to leave her there with a defenseless mother and her newborn children, even if they are sisters. I'm assuming you don't know much about cats and cats giving birth (I mean, who does, right? not many) so I can't blame you too much... you live and you learn, I guess. Too bad you learned the hard way. The very... VERY... hard way D:

oh my god, "half a leg on the floor" this is so horrifying, it's funny

#242 I know quite a bit about cats and their reproductive habits, thank you very much for assuming. I've bred cats in the past, and generally I've found that dominant females can usually protect their own litters from a lone subordinate female without too much difficulty. It would be different if the threat came from, say, a male cat, but the killer in this case was the mother's smaller subordinate sister, who the mother usually never hesitates to attack and chase away when she feels territorial. She just simply seemed to have had little interest in protecting her litter, and when I returned to the room I found her sitting in a different location to where her kittens were, suggesting she had deliberately gotten up and walked away from them when her sister approached them. She appeared rather indifferent to me, and at this moment she's lying side by side with her sister on my bed, so I think they've both forgotten about it already.

This is why I'm a dog person...

That's the most disturbing thing i've ever read in my life

To 218: 216 was asking if the kittens were stillborn.

your still responsible and I blame the kittens dying on you. you should be ashamed of yourself

227: I don't think OP should be ashamed of herself for acting on previous experience, especially when she just said she's familiar with breeding habits.

#249 dogs do it too love, it's a fact of life. darwinism: survival of the fittest.

#246- You can't blame me for assuming when you clearly don't know shit about breeding. I don't care if she was an alpha and her sister was a beta, she just GAVE BIRTH and you expect her to fend off an attacker by herself, after birthing a full litter of kittens? Fact is, she abandoned her kittens to protect herself, and that's sad. Stop trying to blame your cat because YOU are fully at fault. Take some damn responsibility.

#300 I'm not blaming my cat: I really don't care either way what she does regarding her own kittens. If she wants to let her sister eat them that's her choice. YOU clearly don't know anything about breeding, otherwise you'd know that dominant animals lose litters to subordinates far less frequently than subordinates lose litters to dominants (which is the exact reason that any animal wants to be dominant in the first place; dominants have a much better chance of reproducing successfully). How do you think cats as a species survive? Do you think that they can't ever protect their offspring without human interference? You know nothing about cats, period. They survive the same way any species does; dominant individuals are capable of keeping subordinate individuals in line. My alpha cat is more than capable of keeping her sibling in line. Her having recently given birth is irrelevant; she is still dominant and her sister fears and respects her. I don't know if you're under the naïve impression that cats think like humans, but they don't. In cats, and in most non-human animals, dominance doesn't just automatically disappear when the dominant individual is incapacitated in some way. An individual is still dominant unless they have been deliberately challenged for their position and lost, which did not happen in this situation. So my alpha cat would have still been feared and respected by her sibling regardless of her having just given birth, just as she is still feared and respected when she is sleeping or in some other potentially vulnerable situation. The bottom line is she was still dominant to her sister when this incident occurred and could have stopped her, but she chose not to. I am not going to take any blame for that.

Im sorry OP...

Hey bitch stop flipping out on OP. from your picture I'm gonna guess you're one of those obsessive cat owners that's never kissed another human. You are assuming and making an ass out of yourself. When other people have a type of experience and it goes well they follow prior experience and OP has had experience breeding cats before and obviously has done a good job so shut up and stop spewing that OP is a "cat murderer" in your comments cause that actually happens a lot, even strays.

Animal instinct or no should still kill the sister, because it's disgusting that anything would do that to children nature or no.

Really? All animals act like that and crap like that tends to happen. A lot. Give op a break

OP literally just said why she wasn't watching the kittens. I hope one day you have a situation that you have absolutely no control over and see what happens.

Are you stupid?
