Why is my cat suddenly drinking a lot of water?

Table of Contents

Is your cat suddenly drinking a lot of water and there is no identifiable cause? Take your cat to the vet immediately, because there may be a dangerous health problem at the root of excessive drinking. Here are some of the most common causes.

Warm weather

If it’s warm outside or if you have the heating on high, most cats will automatically be drinking a lot of water. This is normal and should not cause panic. Cats need to stay adequately hydrated, so be sure to give them plenty of fluids to drink.

Dry food vs wet food

Cats that only receive dry food have to get their hydration from elsewhere and automatically visit their drinking bowl. Occasionally alternating the dry food with wet food ensures that your cat stays better hydrated.

Running water vs standing water

Some cats dislike standing water and prefer running water from the tap or shower. Does your cat drink every time you open a tap? Then this is probably the cause.

Attention seeking

Are you often away from home or do you give your cat too little attention? In that case, your cat may suddenly start drinking more to seek attention.

Thyroid production too high

An increased thyroid function in cats increases the feeling of thirst. This condition is common in older cats from the age of 11 and can cause long-term kidney and heart failure. If your older cat suddenly starts drinking a lot of water, it’s best to have him tested for excessive thyroid production. An overactive thyroid can be controlled by switching to a raw food diet, medication (Felimazole), nutritional supplements, and limiting iodine in the diet.

Kidney failure is caused by drinking a lot of water

The main reason cats drinking a lot of water excessively is kidney failure. In most cases, the disease progresses gradually, but it can also come on suddenly and have serious consequences. The sooner the disease is diagnosed, the better the vet can control the disease and the better the chances of survival. Kidney failure is almost always caused by excessive drinking and weight loss, so see your vet as soon as possible to have your cat’s kidneys examine

Diabetes

Diabetes can also be a possible cause of your cat’s excessive drinking. Diabetes can be diagnosed through a blood test at the vet. The sooner you catch it, the less chance there is for complications and the better the chances of survival.
