I have a three week old kitten that has been taken care of by mom. There was three in the litter and this one was the smallest but has been doing fine up till the last few days. I noticed she was getting skinny and sneezing once in a while but temp is fine. Today she hasn't been wanting to eat so I started bottle feeding. Is there anything else I can do to help this little girl? I have never had a kitten fade at this age, usually it happens in the first few days..... Thanks for any help.
