This wonderful Tabby showed up at my door about 6 months ago. He is quite vocal and extrodinarily affectionate. He lives indoors and outdoors. He will come in after being out all night and sleep hard about 8-10 hours straight after eating. Two days ago he came in and crashed longer than usual, when I went to see about him he would barely arouse. He has no appetite, he will drink a little water from time to time, but mostly he just stays in one position in his bed. He is not vocal at all, he won't even purr. have checked him over well, I see no injury, swelling of the abdomin, there is no vomitting or diarrhea. Does anyone have any ideas?
