Why Does My Cat Keep Taking Her Sister's Kittens When She Has 3 Of Her Own?

by Kathryn

I have 2 female cats who are sisters from the same litter. Both cats had their own litters within hours of each other - one of them had 3 kittens and the other had 5.

The cat with the smaller litter keeps taking kittens from the larger litter! When I try to take them back to their mother she becomes aggressive with me and sits on the kittens she has taken!

How do I stop her taking more and is this normal? The mother of the larger litter doesn't seem bothered that her kittens are being taken.

Reply from Liz (Editor): This is unusual, as far as I'm aware, but I can't envisage it being a huge problem as long as all the kittens are being fed adequately and cared for.

Is the "thief" cat (for want of a better expression!) trying to take all of her sister's kittens or is it just one or two? Is it constant or occasional? It may be that the "thief" cat has stronger maternal instincts - or she may even be thinking she's "helping her sister out" because she's got the bigger litter.

If it does get to the stage where it looks as though the kittens aren't getting enough milk you may have to separate the two mothers and litters completely. But as long as everything seems fine then I don't think it is a problem.

Thank you for your submission.
