You did the right thing in getting her spayed. I think it's nice that you kept one of her kittens from her first litter, as it will be company for her and it's better, if you have more than one cat, that they're related, as they will get on together. She's just being normal in doing what you describe. Don't forget, she's just lost a litter really and so her hormones are a bit up the creek! She'll settle down soon, so don't worry, just enjoy her and the kitten's company. If they're anything like my mother cat and her 2 babies (now 2 & a half years old), they fight like h**l and then sit & wash each other as though they're saying, "I love you, really!" (Don't forget to get the kitten neutered, though, will you?) K
