Kidney failure is a relatively common health issue that many sweet senior cats face, although it can affect all age groups. If your kitty is experiencing kidney failure, don't be surprised if you notice big changes in her temperament and attitude -- think uncharacteristic exhaustion and listlessness. Poor dear.

Appetite Loss

One prominent behavioral sign of kidney failure is appetite loss. If your fluff ball has always possessed the voracious appetite of a football player and suddenly always ignores her food bowl and treats, something is up. The marked decrease in appetite also frequently triggers dramatic weight loss in felines, as well.


If your precious pet all of a sudden always seems down in the dumps, kidney failure could be at fault. The disorder often brings upon depression even in the liveliest, most jovial of felines. When your cat randomly has zero interest in the things that used to bring her joy, don't just ignore it. Whether it's staring outside at the squirrels and the birds or playing all day with her catnip-stuffed toys, a loss of interest in pastimes often points to a serious problem.


You may notice that your kitty simply has no energy anymore. She might always seem exhausted and lethargic. She might actually even sleep the whole day away, hiding in the darkest nooks of your home. She just doesn't seem like herself and things don't seem right at all. Don't just blame a drastic energy level change on the natural aging process -- investigate the situation further for your precious pet's sake.

Non-Behavioral Symptoms

Behavioral symptoms aren't the only problems that cats with kidney failure experience. If your cat's behavior just seems out of sorts, keep your eyes open for other unusual health signs, including unusual thirst, frequent or infrequent urination, throwing up, diarrhea, halitosis, messy or lackluster-looking fur and overall feelings of weakness. Upon taking in any health or behavioral abnormalities in your cat, seek veterinary attention as soon as possible. When it comes to your pet's health, remember, the earlier you pinpoint a troubling issue, the better. Don't be leisurely and take any chances with your cat's well-being and happiness.

Always check with your veterinarian before changing your pet’s diet, medication, or physical activity routines. This information is not a substitute for a vet’s opinion.
