Ok thank you so much. It just came on so suddenly I was at a loss. I locked him in the bedroom with egg whites mixed with chicken broth, water, and a litter box...mostly to give him a break from the kitten lol
This morning I found my 4yr old cat in the same place he was when I went to bed which is unusual because he usually wakes me up. Then I realized that I haven't seen him eat in three days (I have a kitten so I can't monitor his food bowl because they occasionally switch). I tried to bribe him...
