my 6 kittens that i'm hand raising (see my other post) are starting to get teeth in. i tried giving them some canned kitten food and they just walked in it and got it all over them. i dipped their mouths in it and even tried spooning it in, they want no part of it. they also started going to the bathroom on their own so i've added a litterpan. i've tried everything to get them to start eating solid food, they just wait for milk and i'm scared their going to starve, any advice?
