Why is My Cat Constantly Thirsty?

Are you worried your cat could be drinking too much water?

An aged cat with unquenchable thirst needs to be screened by a veterinarian for feline hyperthyroidism. Excessive thirst alone is not a telltale sign pointing to feline hyperthyroidism, but constant water intake is not a symptom to ignore.

Before the panic begins to rise, a few extra moments at the water bowl is nothing of concern. If you’re routinely finding your elderly feline friend drinking from dripping faucets…and the toilet, fish tank, water glasses, and the questionable puddle next to the water heater in the basement – it’s time to call your veterinarian to schedule a screening for feline hyperthyroidism.

Cats want to drink clean water from a familiar bowl or dish. If your cat is suddenly seeking unsavory water from other sources, think of the water heater puddle in the basement or outdoor stagnant water, this could be a major clue about your cat’s changing health. If your water bowl is plastic, this could be the culprit behind your cat’s unusual drinking habits. Some cats have an aversion to drinking from plastic water bowls, so switching to ceramic, glass, or stainless-steel bowls may help.

It can be tough to differentiate healthy versus not when your cat playfully ventures out to chug a little bathwater or when your cat is a serial kitchen sink sipper. The occasional unorthodox hydration session is no call for alarm. It’s the elderly cat furiously seeking every hint of moisture despite having a devoted caretaker providing fresh water that needs to explore the possibility of feline hyperthyroidism.

If you’re unsure if your cat’s water intake is out of control, your cat’s litter box will tell the tale. You will notice an obvious influx in litter box changes. An older cat suffering from feline hyperthyroidism may make more frequent trips to the litter box or even have accidents inside the house.

Your cat’s constant water intake may be a sign of health problems unrelated to feline hyperthyroidism entirely; only a veterinarian can make an official diagnosis. If your cat is experiencing excessive thirst, schedule an appointment with your veterinarian for a screening for feline hyperthyroidism.
