What Does It Mean If My Cat Is Drinking More Than Usual?

If you've noticed your cat suddenly spending more time at the water bowl, you might be wondering what’s going on. Cats are typically known for their low water intake, so an increase in drinking can be a sign that something is amiss. While it's important not to panic, it's equally crucial to understand the potential reasons behind this change and know when to seek veterinary advice. Let’s dive into why your cat might be drinking more than usual and what you can do about it.

Possible Reasons for Increased Thirst

Environmental Factors

Sometimes, the answer is simple. If the weather is hotter than usual, your cat might just be hydrating more to stay cool. Similarly, if you’ve changed their diet to include more dry food, they might need extra water to balance their hydration.

Dietary Changes

A switch to a diet with higher salt content or more dry kibble can lead to increased thirst. Dry food contains less moisture than wet food, so cats need to drink more to compensate.

Medical Conditions

Several medical conditions can cause increased thirst in cats. These include:

  1. Diabetes Mellitus: This condition affects the body’s ability to regulate blood sugar levels, leading to increased thirst and urination.
  2. Kidney Disease: As cats age, their kidney function can decline, resulting in greater water consumption.
  3. Hyperthyroidism: This is a condition where the thyroid gland produces too much hormone, speeding up the metabolism and causing increased thirst and appetite.
  4. Urinary Tract Infection (UTI): Infections in the urinary system can make your cat drink more in an attempt to flush out the bacteria.


If your cat is on medication, increased thirst could be a side effect. Always check with your vet if you notice any changes after starting a new medication.

When to See the Vet

If your cat’s increased thirst is accompanied by other symptoms such as weight loss, changes in appetite, lethargy, or frequent urination, it’s time to visit the vet. Even without additional symptoms, a noticeable change in drinking habits warrants a check-up to rule out any serious conditions.

What You Can Do at Home

Monitor Water Intake

Keep track of how much water your cat is drinking. Measure the amount you put in their bowl and how much is left at the end of the day. This information will be useful for your vet.

Check Their Diet

Ensure your cat’s diet is balanced and consider incorporating more wet food to help with hydration. Wet food contains a higher moisture content, which can naturally reduce the need for drinking large amounts of water.

Provide Fresh Water

Make sure your cat has access to fresh, clean water at all times. Cats can be picky about their water source, so consider using a water fountain to encourage drinking.

Observe Other Symptoms

Keep an eye out for other changes in behavior or health. Noting any additional symptoms can help your vet diagnose the underlying issue more quickly.
