I have 5 kittens, they’ll be 9 weeks old on Tues. 4 of them are no longer nursing & are eating wet & dry food. I have 1 hold out, she has no interest in the wet food & still tries to nurse mom. I can see that mom is trying to wean her. She’s very tiny & I’m concerned that once mom will no longer nurse her she won’t be getting enough. She eats a little dry food. I’ve tried KMR but she doesn’t seem to like it. What can I do to help her be more interested in solid food? She’s 7 weeks in the pic.
