Thanks to all for your answers about Oreo's food.
Another question. About a month ago, my 12 year old diabetic cat, Oreo, was hospitalized (vet and hospital on same premises) because he was vomiting after he ate. It was the color of his DM Purina food. Vet felt he should be hospitalized. He was in hospital for 4 days, on iv, xrays, blood work, etc. They couldn't find anything. The vet said he never vomited. Cost - close to $2,000 for 4 days for procedures and boarding. Vet said if he continues to vomit they would have to do ultra sound and perhaps exploratory surgery. So I've been watching Oreo and he vomits about 2 days a week. I haven't reported this to the vet because I know he will be back in the hospital and I can't afford it. I've check at home to make sure he's not finding things stuff/objects to eat that may be causing this vomiting. I just don't know what to do at this point since I don't want exploratory surgery. Sometimes, I feel I'm being ripped off with vets. Has anyone experienced this with their diabetic cat.
