My cat had kittens late March but they died at 3 weeks of age. Now my mom's sister just had 3 babies and my cat keeps stealing one of them. The thing is, she isn't trying to nurse it or mother it --- she just leaves it in another room by a window and stays away from it. I thought well maybe she thinks it's her lost kitten but she doesn't act that way. She just leaves it where she puts it. It's becoming really annoying. How can I put a stop to this so she does not accidentally kill my other cats new babies?
