My 14 year old cat DeeJay is on a canned food only diet, has been that way for 4 years. All the sudden the last couple of days she is eating maybe one or two licks of her canned, then rushes out to finish off my only dry food cats dish (Mini never finishes her bowl). She had bloodwork done a week ago and it was all normal except slightly (2 points) elevated BUN. I have tried a couple of different canned foods, but to no avail all the sudden she doesn't want it. I've tried warming it up, tried parmasan cheese, any other ideas on what to do to get her to eat the canned again? I even tried mixing some high cal stuff in with her canned and she totally snubbed it.
