My cat was vomiting almost everyday for about one week. It had lumps of fur and undigested food. Yesterday he vomited in the early morning and has not done so since. He is unusually lazy and wants to sleep or just stare off into space. He is eating and using the litter box. He has diarrhea (just started today) and walks very slowly when he moves around. He will let me touch him anywhere but still wants his own space. He has lost all energy. Help if you can. He is an indoor cat.
