What Is Polydipsia in Cats?

If you think that polydipsia might translate to "multiple dips" you’d be pretty much correct – as in multiple dips from the water dish. This dipsy sounding word refers to constant or excessive drinking as a result of thirst, which may indicate an underlying health condition.

You might not notice it all at once. Maybe you’re working on your laptop at the kitchen table when you notice your cat padding past you for the third or fourth time for a drink from his water bowl – even before you’ve had your second cup of coffee. You start to wonder what’s up.

Did Felix have too many anchovies on his pizza? Or is this thirst a real cause for concern?

Learn what the signs are that you need to seek veterinary help when your cat develops insatiable thirst – and what you should do about it.

All About Cats + Excessive Thirst

If Kitty's had a recent bout of digestive upset – such as vomiting and diarrhea – chances are the increased water intake is due to a normal need to rehydrate. When your cat continues to thirst more than usual over several days, the cause might be an underlying health condition.

However, there are several other conditions that can cause Fluffy to visit the watering hole on repeat.

As with humans, blood sugar problems like diabetes mellitus can cause excessive thirst in cats. When too much glucose builds up in the blood the excess is excreted through more frequent urination. Resulting dehydration causes a person – or kitty – to drink more. Since cats often tinkle in private, you may only notice their increased thirst.

Some cats, especially senior ones, develop chronic kidney disease (CKD). It's a common, progressive condition that, according to vet Dr. Celeste Clements, affects three out of every ten cats. The key to improved survival and quality of life is recognizing the signs, the first of which are often excessive thirst and urination.

Hyperthyroidism is a common disease affecting cats of middle and older age. According to Cornell’s College of Veterinary Medicine, the most common signs of hyperthyroidism are "weight loss, increased appetite, and increased thirst and urination.” Other, developing signs may include their coat appearing "unkempt, matted, or greasy."

Lastly, urinary tract infections (UTIs) can occur in male and female felines of any age, though this affliction is less common in very young cats. Besides frequenting the water dish, your cat may display changes in urinary behavior like going outside the box, straining to urinate, or producing less urine.

Products like health-monitoring PrettyLitter can help you keep an eye on issues like these, in addition to keeping an eye on your precious kitty's daily habits, mood, and behaviors.

These are a handful of conditions that could cause your cat to start wearing out the floorboards tiptoeing back-and-forth for a drink. Learning all about cats and their potential medical issues is a daunting endeavor, but as an informed pet-parent, you can take the best care of Fluffy by knowing what to watch out for.

Know When to Go to the Vet

If the weather is very hot or if Felix has been engaging in a mad display of acrobatics, he’ll understandably work up a healthy thirst. Heat and exercise aside, if your cat continues to pound the H20 with or without other symptoms, you should pay a visit to the vet.

If your vet recently prescribed a new medicine for your cat, be sure to inquire if it might be linked to your cat’s extreme thirst. Drugs like diuretics can increase thirst, and such thirst can even be a sign of a dangerous side effect of pain meds.

Any condition that causes polydipsia may be serious and should be monitored or treated under veterinary supervision.

Keeping Up With Kitty

Cats are creatures of habit. When you notice a change in your cat's eating or drinking habits, urination or bowel movements, you may need to take a closer look at his health. That goes for behavioral changes, too.

Your cat’s vocalization can provide a clue that something’s off. If Maximilian’s meow sounds more plaintive than ever, something might hurt – or he might be feeling less like the King of the Jungle due to stress. Is your normally outgoing tabby spending his days hiding under the bed? Clingy calico more needy than usual?

Don’t ignore your cat’s potential need for different food, more attention, or professional help. Remember that your cat depends on you for his care.
