HELP! How Much Pee Is Too Much Pee?

"Hi Dr Paola,

My female cat, Kiwi, is 15 years old and has always loved water and drinking it. She eats dry food. I’ve noted she’s urinating 5 times a day. Is this within range for the amount she’s urinating?"

Hi Ange!

Five trips to the litter box each day doesn't automatically fall outside the normal range, especially if Kiwi has always loved drinking water and eats a dry food diet. Cats can vary quite a bit in how often they urinate, so the number of visits to the litter box is only one piece of the puzzle. What matters more is whether she's producing unusually large amounts of urine and if her water intake has increased compared to what has always been normal for her.

As a general guideline, healthy cats drink around 40 to 60 mL of water per kilogram of body weight each day, although cats eating dry food often drink closer to the higher end of that range because kibble contains very little moisture. Consistently drinking more than 100 mL/kg/day is considered excessive and deserves further investigation. Normal urine production is approximately 20 to 45 mL/kg/day, so for a 4.5 kg (10 lb) cat, that's about 90 to 200 mL of urine per day. Since most pet parents aren't measuring urine output, the litter box can provide helpful clues. Five average-sized clumps spread throughout the day could be completely normal, whereas several very large, heavy clumps may suggest she's producing more urine than expected.

Because Kiwi is 15 years old, it's also worth considering whether this is simply her lifelong habit or a recent change. Increased thirst and urine production are common early signs of conditions such as chronic kidney disease, hyperthyroidism, and diabetes mellitus, all of which become more common as cats age. If you've noticed she's drinking more than she used to, the urine clumps have become larger, or there have been any other changes in her appetite, weight, or energy level, I'd recommend scheduling a veterinary examination. A physical exam, blood work, and a urinalysis can help determine whether her drinking and urination are normal for her or if there's an underlying condition that would benefit from early treatment.

I hope this helps!
