We have a kitten at the shelter right now that was doing really well, but over the last week she appears to be going down hill. Her mother is constantly snuggling with the kitten, but the kitten doesn't seem intrested in eating. We have tried to bottle feed her, she won't take that. She's not crying like she's hungry? Does failure to thrive happen that late? I've seen kittens pass in the first week, but at 3-4 weeks seems a little odd to me. Any ideas?
