Hi. My cat is 5 yr old, obese and diabetic. I noticed fresh blood in her stool yesterday and took her to the emerg vet, who thinks it is gastritis. She seemed to be constipated for the past few days so maybe that's the problem. She is on antibiotics and anti-inflammatory meds now but I am worried about what to feed her. Her appetite is good and she isn't drinking anything other than the water that I add to her food. I was giving her Nature's Variety Instinct raw (frozen) food. (The vet had recommended the Hill's m/d stuff but I don't like the ingredients) But now I wonder if I should go back on the vet food. Advice would be appreciated!
