My 17 year old cat, Thea, was diagnosed 2 weeks ago. She is on 2 Glipizide, twice a day and Benazepril once a day and was eating Purina DM Wet the first week. On her return visit, her numbers were normal. The vet told me to keep her on the medication, but to feed her anything she would eat to get her nutrition back up. I have been giving her Fancy Feast Classics. On Thursday, she slept the entire day and night, but did eat morning and night. I woke her a couple of times, but she refused food. Yesterday, she ate very well and was alert all day. Today she is lethargic again and has eaten almost nothing. I coaxed her to eat some of the friskies wet food I still had on hand, but she only licked up the gravy. Any suggestions on what I can tempt her with?
