My 23-yr-old indoor-only cat Muzak has been eating less and less for a month, last three days nothing. Vet is doing bloodwork. I just got him to eat! with warmed food. Looking for a heated food dish for INDOOR - outdoor bowls heat too low. I thought of a small human heating pad underneath the bowl - might need a different bowl made of different material. Or are there indoor heated bowls? Any advice appreciated. Thank you!
