I posted about a week ago, about my spayed semi-feral, going after her then 7 1/2 week old kittens, well she is still nursing one kitten. She does not want the others. I have had to separate them. The one she favors, just wants to nurse. she doesn't want to wean. I have been trying to get her, to eat separate from Mom. she had a little food this morning mixed with milk. She is now almost 9 weeks old. Is this unusual? How can I encourage her to eat?
