My cat (Cali) has her first (and hopefully last) litter of kittens (they'll be four weeks on Wednesday) and her entire demeanor has almost completely changed. She used to be kind to everyone and every creature, but not so much anymore. She's overly affectionate towards humans, but doesn't care for our other cat. She claws and hisses at him at sight (we've kept them separated since she had the kittens, but she occasionally escapes into the living room for a few minutes). The first time they saw each other was the day after delivery, and that's when we noticed the behavior first. She had them under one of our beds, and less than 24 hours later she'd already moved them three times. She doesn't carry them by the scruff though. She carries them by the front or side of the neck or the ear. She also lays on them. We've had to pick her up off of the baby or babies while they're screaming at the top of his or her lungs. As soon as we move Cali she'll lay right back down on the baby/babies, even if we did move her to a very clear space. She also randomly claws and bites at her kittens. At first I thought they were playing or punishment, but then we realized she even does it when the babies are eating or sleeping. She also will not allow them to eat for more than five minutes. I had to pet her one time to allow her kittens to eat because she's just not interested. She's done this the entire time she's had them. So it isn't her weining them I don't think. She'll get one baby out and just leave him or her. It's never the same kitten. Two weeks ago she kept bringing me her kittens (on top of my bed) and would just leave them. She would go lay down on the other bed, and I would have to have my fiance go get her because she wouldn't come feed them and would keep putting them up there with me, no matter how many times we put them back where she had them before they were on the bed. As of right now, I'm most concerned with her laying on the babies, refusing to let them finish eating, and her randomly attacking them. Is there anything I can do?
