Why is my cat peeing watery urine and drinking a lot of water?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 15 years and 11 months old | 6 lbs

My cat occasionally ignores her box but what I've found doesn't appear to be normal pee. I'm used to a certain viscosity/yellow color and this was practically water. She has multiple water bowls and drinks often in addition to water added to her canned dinner. She also has access to about a cup of dry kibble through the day.

I'm sorry to hear that Lelia has been having these issues! Diluted water-like urine can occur due to increased water consumption and/or an inability of the kidneys to absorb this water appropriately. This can sometimes lead to cats experiencing inappropriate urination outside of the litter box. Some of the common causes of increased drinking and urination include kidney disease, urinary tract infection, diabetes, hyperthyroidism, liver disease or cancer. At this point, I do recommend taking Lelia to her vet for an exam and lab testing (CBC, chemistry, urinalysis, T4 - thyroid) to get to the bottom of this issue by assessing her organ function. I hope that all goes well!

    There are several diseases which can male your kitty drink excessively. The fact that he pees and poos in places other than the litter box as well, is indeed a sign that he is not healthy. Excessive drinking and urination are cardinal signs of either diabetes or kidney disease. These would be the most common causes. Please take Massacre to your veterinarian for an exam, a urine test, and blood tests. Diabetes can be treated very well and there are quite a few cats that go into remission after being on insulin for a while and with diet. Kidney disease can also be treated to slow down deterioration of the kidney function. Untreated, both diseases will shorten your kitty's life. Please take Massacre to a vet soon.

    This could be due to a could of things. He could have diabetes, kidney disease, hyperthyroidism, a UTI, or bladder stones. I would have your cat seen by a vet today for a physical exam, blood tests, and a urinalysis to diagnose what is causing his symptoms. Once a diagnosis has been made, the vet can prescribe treatment for him.

    The most common reason for a cat this age to be drinking a lot and subsequently urinating a lot is almost always diabetes. This can be easily tested for with some routine blood and urine testing. I suggest you get Fairy to the vet as soon as possible so you can get a proper diagnosis. Hope this helps. Best wishes.
