My Cat is Drinking a Lot of Water [11 Reasons]
If you’re scratching your head wondering why your furry feline friend has suddenly become a water guzzler, you’re not alone.
In this quick read, we’ll dive into the possible reasons behind your cat’s increased water intake, from harmless quirks to potential health concerns.
So, let’s get to the bottom of this cat hydration mystery together!
My Cat is Drinking a Lot of Water
Cats may drink excessive amounts of water due to various underlying health conditions such as chronic kidney disease, hyperthyroidism, diabetes mellitus, and other illnesses.
Monitoring your cat’s water intake frequency can help you determine if they are drinking more than normal and may indicate a need for veterinary consultation.
Increased thirst in cats can be a symptom of kidney disease or diabetes mellitus and should be checked and diagnosed by a vet, especially if accompanied by other signs of illness.
It’s important to never withhold water from your cat unless directed by your veterinarian as excessive, frequent water drinking isn’t common in cats and may indicate potential concerns.
Cats need to consume about 4 ounces of water per five pounds of lean body weight per day, so the average 10-pound cat should drink about one cup of water per day.
However, cats that eat wet food, which can contain up to 80% water, may drink less, and cats that eat dry food usually take more of their daily water requirement in by drinking.
Let’s break it down further…
Potential Reasons for Increased Water Drinking in Cats
Here are some of the most common reasons for increased water drinking in cats:
1. Dietary Changes
Cats may increase their water intake due to dietary changes.
For example, if you’ve recently switched your cat’s food to a dry kibble, they might feel the need to drink more water to compensate for the lack of moisture in their diet.
Cats are naturally designed to obtain moisture from their prey, so a dry diet can leave them feeling thirsty.
It’s important to ensure that your cat has access to fresh water at all times, especially if they’re on a dry food diet.
2. Dehydration
Dehydration is another common reason for increased water drinking in cats.
Cats can become dehydrated due to various factors such as illness, vomiting, diarrhea, or excessive urination.
When they’re dehydrated, their body naturally signals them to drink more water to rehydrate.
If you notice your cat drinking more water than usual, it’s essential to monitor their hydration levels and consult a veterinarian if you suspect dehydration.
3. Hyperthyroidism
Hyperthyroidism, a condition where the thyroid gland produces an excess of thyroid hormone, can also lead to increased water intake in cats.
The overproduction of thyroid hormones can cause an increase in metabolic rate, leading to increased thirst and urination.
If your cat is drinking more water, along with displaying other symptoms like weight loss, increased appetite, or restlessness, it’s crucial to have them evaluated by a veterinarian for possible hyperthyroidism.
4. Hot Weather
Just like humans, cats tend to drink more water in hot weather.
Cats regulate their body temperature through panting and sweating through their paws, which can cause them to lose moisture.
To compensate for this loss, cats instinctively drink more water to cool down and stay hydrated.
During hot weather, ensure that your cat has access to plenty of fresh, clean water and a cool environment to help them stay comfortable and hydrated.
5. Diabetes mellitus
Well, just like humans, cats can also develop diabetes mellitus. This condition affects the way their bodies process sugar or glucose.
One common symptom of diabetes in cats is increased thirst, leading to increased water intake.
The excessive thirst is caused by the body’s attempt to flush out the excess sugar through increased urine production.
If you notice your cat drinking more water than usual and also urinating more frequently, it’s a good idea to consult with your veterinarian for proper diagnosis and treatment.
6. High-Salt Diet
Cats are obligate carnivores, which means their natural diet consists mainly of meat.
When cats consume a diet that is high in salt or sodium, it can lead to increased thirst.
High-salt diets can be found in certain commercial cat foods or even in human foods that cats might get a taste of.
While a small amount of salt is necessary for cats, excessive salt intake can disrupt the balance of fluids in their bodies and result in increased water consumption.
It’s important to provide your cat with a balanced diet that meets their nutritional needs and consult your veterinarian about the appropriate diet for your furry friend.
7. Stress or Anxiety
Just like humans, cats can also experience stress and anxiety.
Changes in their environment, routine, or the introduction of new pets or people can trigger stress in cats. One way cats may cope with stress is by increasing their water intake.
Stress can affect their hormone levels, leading to an increase in the production of urine, which in turn increases their thirst.
If you notice your cat exhibiting other signs of stress, such as hiding, excessive grooming, or aggression, it’s important to address the underlying cause and provide a calm and secure environment for your cat.
8. Medication Side Effects
Certain medications can have side effects that impact a cat’s water intake.
Some medications may affect their kidney function, which can result in increased thirst and urination.
If your cat has recently started taking a new medication and you notice changes in their water consumption, it’s essential to consult with your veterinarian.
They can evaluate the medication regimen and determine if the increased water intake is related to the medication or if further investigation is necessary.
9. Liver (hepatic) disease
When a cat has liver disease, such as hepatitis or cirrhosis, it can affect their overall health and lead to increased water intake.
The liver plays a crucial role in various metabolic processes, including the production of proteins and the removal of toxins from the body.
When the liver is compromised, it may not function properly, resulting in an imbalance of fluids in the body.
This imbalance can cause dehydration, leading the cat to drink more water to compensate for the loss.
Additionally, liver disease can also cause an increase in urination, further contributing to the need for increased water intake.
10. Kidney (renal) Dysfunction
Kidney dysfunction is a common condition in cats, especially as they age. The kidneys are responsible for filtering waste products and regulating fluid balance in the body.
When the kidneys are not functioning optimally, they may fail to concentrate urine effectively, leading to increased water intake.
Cats with kidney disease often have increased thirst as their bodies try to compensate for the impaired kidney function.
This increased water consumption helps to flush out toxins and maintain hydration.
It is important to note that increased water intake alone is not a definitive sign of kidney dysfunction, and a proper veterinary diagnosis is necessary to confirm the condition.
11. Urinary tract disease
Urinary tract disease in cats encompasses various conditions, including urinary tract infections, bladder stones, and feline lower urinary tract disease (FLUTD).
These conditions can cause discomfort and inflammation in the urinary tract, leading to increased water intake.
Cats with urinary tract issues may drink more water to dilute their urine and alleviate the discomfort caused by inflammation.
Additionally, increased water intake can help to flush out bacteria or crystal formations that may be present in the urinary tract.
However, it is important to understand that not all urinary tract diseases result in increased water drinking, and other symptoms like frequent urination or difficulty urinating should also be considered.

What to do if a Cat is Drinking a Lot of Water
If your cat is drinking a lot of water, it could be a sign of an underlying health issue, so it’s important to address it.

The vet can run tests to determine if there’s an underlying medical condition causing the excessive thirst.
In the meantime, monitor your cat’s behavior and look for other symptoms like excessive urination or changes in appetite.
Keep an eye on the litter box for any unusual patterns as well. It’s crucial to stay proactive and seek professional guidance to ensure your cat’s well-being.
