I am fostering a mother cat with 6 kittens. I picked her up from the shelter on Wednesday and she hasn't eaten at all since early on Wednesday (before I got her). She has an upper respiratory infection, they told me, and I think she has worms too. I've given her deworming medication, but I still can't get her to eat. Her eyes are quite running with gunk and she seems to be keeping them closed most of the time - probably are painful. I've tried a humidifier, a warm compress, eucalyptus oil, tuna, heated canned food, tuna water, and even put the food in her mouth. She just spits it back out. I'm wondering how I can get her to eat and how long she can go without eating before she has no milk left for the kittens. It's Friday now, so it's day 3 of no eating. I did see her have a small drink last night, so that's something... Any thoughts??
