If you’ve suddenly noticed your cat spending more time at the water bowl or finishing it faster than usual, it’s worth paying attention. Increased thirst in cats known as polydipsia isn’t always an emergency, but it’s often one of the earliest signs that something in their body isn’t quite right. While some causes are harmless, others may need prompt veterinary attention from trusted professionals like vets Keysborough.
Cats are naturally subtle when it comes to showing illness. So changes in drinking habits can be one of the few visible clues that something deeper is going on.
Normal vs. Increased Water Intake
On average, a healthy cat drinks about 40–60 ml of water per kilogram of body weight per day. However, this can vary depending on diet, weather, and activity level. For example, cats eating dry kibble tend to drink more water than those on wet food diets.
You might start to suspect a problem if:
- Your cat is visiting the water bowl much more frequently
- The water bowl is emptying faster than usual
- Your cat is drinking from unusual places like taps, sinks, or toilets
- You notice increased urination along with thirst
When these changes appear suddenly or continue for more than a few days, it’s a good idea to consult vets Keysborough for a proper health check.
Common Reasons Your Cat May Be Drinking More
There are several possible explanations for increased thirst in cats, ranging from mild to serious.
1. Hot Weather or Diet Changes
During warmer months, cats naturally drink more water to stay hydrated. Similarly, switching from wet food to dry food can increase water intake. These are usually harmless reasons.
2. Kidney Disease
One of the most common causes of increased thirst in older cats is chronic kidney disease. When the kidneys are not functioning properly, they lose their ability to concentrate urine, leading to more water consumption.
3. Diabetes Mellitus
Diabetes is another serious condition that often shows early signs through excessive drinking and urination. Cats may also show weight loss despite a good appetite.
4. Hyperthyroidism
An overactive thyroid gland can speed up metabolism, causing increased thirst, hunger, weight loss, and restlessness.
5. Urinary Tract Issues or Infection
Bladder infections or inflammation can sometimes lead to changes in urination patterns, which may also affect drinking habits.
6. Medication Side Effects
Certain medications, especially steroids, can increase thirst as a side effect.
When Should You Be Concerned?
Occasional changes due to heat or diet are usually not a problem. However, you should contact vets Keysborough if you notice:
- Persistent increased thirst lasting more than 2–3 days
- Sudden weight loss or gain
- Lethargy or changes in behaviour
- Increased urination or accidents outside the litter box
- Vomiting or loss of appetite
Early diagnosis can make a huge difference in treatment outcomes, especially for conditions like kidney disease or diabetes.
What Will the Vet Do?
When you visit a veterinary clinic, your vet may perform:
- Physical examination
- Blood and urine tests
- Kidney and liver function tests
- Thyroid hormone testing
- Blood glucose testing
These tests help identify the underlying cause so treatment can begin as soon as possible.
Supporting Your Cat at Home
While waiting for your vet appointment, you can:
- Ensure fresh water is always available
- Monitor how much your cat is drinking (if possible)
- Avoid sudden diet changes
- Keep a note of other symptoms
But remember, home care is not a substitute for professional advice from vets Keysborough if symptoms persist.
Conclusion
A cat drinking more water than usual should never be ignored. While it can be something simple like heat or diet changes, it may also be an early warning sign of more serious health conditions. The safest approach is always to monitor closely and consult vets Keysborough for a proper check-up. Early detection can protect your cat’s long-term health and ensure they stay happy, hydrated, and healthy.
