Why is my cat with kidney disease not eating her usual food?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Female | spayed | 8.75 lbs

My cat who loves to eat her hills science diet g/d wet food, didn't eat this morning. Other mild symptom is sleeping, but not lathargic. She did eat her food when I hand fed her and also ate baby food just fine. She's not a picky eater. Last vet check was 6 days ago. All looked good. She does have stage 2 kidney disease, 2.0 creatine. Kidney panel blood work came out better then last time. I don't think it's her kidneys. She usually begs for her food. I don't know what's wrong?

Unfortunately, this could be a number of things. The first thing I tend to think of in older cats in which renal disease has already been diagnosed is the development of a urinary tract infection, and especially if urinary signs (urinating outside the box, increased frequency of urination, increased drinking, etc) that should be considered. Kidney disease predisposes them to the development of UTI's, and they can quickly become serious in these patients as often times it's not a LOWER UTI (i.e. a bladder infection) but an UPPER UTI (i.e., involving the kidneys). At this point she's only missed one meal, so I wouldn't panic yet - especially because she did eat when you hand fed her. However, do be diligent and consider whether she needs another checkup (to include a urinalysis and potentially x-rays or ultrasound) if this keeps up more than 24 hours, since it's such unusual behavior for her.
