As a responsible cat owner, it’s important to keep an eye on them to see if they are healthy and well.

This can include making sure their vaccinations against certain diseases are up to date as well as giving them the right amount of food so they aren’t overweight.

But one important factor to watch out for is how much water they are drinking because if you have noticed them drinking a lot, it could be a sign of serious health issues.

Petplan veterinary surgeon Brian Faulkner shares three reasons for increased thirst in cats and why you shouldn’t ignore it.

Why is my cat drinking so much water?

Diabetes

Brian said: “Type 1 diabetes is very rare in cats, but older or overweight felines are often diagnosed with Type 2, due to the pancreas becoming less efficient as they age. Male cats also appear to be at more risk, although vets are not yet exactly sure why.

“Diabetic cats become very thirsty because there’s too much sugar in the urine, which, in turn, draws water out of the body.

“Some breeds – such as the Burmese – are more vulnerable to diabetes than others. But for all cats, at every life stage, the risk lessens with good levels of activity (especially for indoor cats) and a complete, balanced diet.”

Kidney disease

Brian advises: “Extreme thirst is usually the first symptom of kidney disease in cats. But as the toxins build up in their blood, your cat is likely to eat less, feel nauseous or even be sick.

“It’s important to seek your vet’s advice if you notice any of these symptoms.

“Accidental poisoning can also cause kidney damage in cats of any age. Anti-freeze is a common culprit, and should always be kept out of your pet’s reach.”

Hyperthyroidism

Brian explains that older cats can develop an overactive thyroid gland, a condition known as hyperthyroidism.

He went on to say: “Metabolic rate, vitality and coordination are all controlled by the thyroid gland – so if it’s working more frantically than it should be, your cat will be irritable and skittish, and may even pant.

“Other symptoms of hyperthyroidism include drinking and weeing more frequently, and losing weight, despite eating more.

“Hyperthyroidism can occur in any breed, at any age, but it’s more likely to develop in cats as they get older. Your vet will be able to recommend thyroid medication that can help.”

Other reasons your cat might be drinking more water than usual include “urinary tract infections, liver disease, or increased thirst after a bout of vomiting or diarrhoea.”

Always speak to a vet if you have any health concerns about your cat or you can find more information on the Petplan website.
