I have a cat who just had a litter of kittens on 4/23/05, by c-sect. she seems to be trying to go into heat, miewing and rolling ect. she wont lose her milk or stop caring for her kittens? how do I stop her from doing this? how can I tell if she does lose milk? her teets are really red, she still looks like she is nursing them, but her kittens dont look so fat today, she had milk yesterday.
