Why Is My Russian Blue Cat So Thirsty And Drinking A Lot Of Water?

The following causes include both normal conditions and serious health issues that can be dangerous to your pet’s health.

Hence, without further ado, the following are the probable causes of your Russian blue cat’s excessive water drinking:

Chronic Kidney Disease/ Kidney Failure

Chronic Kidney Disease or CKD is common in 20% to 50% of cats mostly over the age of 15 to some degree. Vets claim all the cats over the age of 15 years will certainly face this problem, because as cats are committed carnivores their kidneys work extra hard for filtration.

The kidneys soon begin to fail to cause an unbalance of the water levels in the felines’ body producing more dilute urine. So, Cats drink more water to keep hydrated.

In addition, cats also begin to lose their ability to concentrate their urine, making them drink water more often. Some other symptoms of CKD are weight loss, appetite loss, bad breath, vomiting, and seizures.

Blood tests and urine tests will help to confirm the condition, which will be irreversible and progressive. The treatment can only sustain the current functions of the kidneys, by dietary change, more water intake, and medications.


Problems in the Thyroid glands are not limited to us humans, Russian blues along with other cat breeds suffer from it too.

Particularly, cats suffer from hyperthyroidism, where the hormone called thyroxine produced from the thyroid glands due to a tumor becomes hyperactive. The hyper activism of this hormone causes another hyperactivity of the cats’ metabolism.

As a result, your pet faces weight loss, high blood pressure, high heart rate. But, the less known symptom is polydipsia. As the name suggests polydipsia is the term given to excessive thirst. This excessive thirst is caused due to increased kidney filtration due to high blood pressure from hyperthyroidism.


Diabetes in cats. Wait, what? Cats can have sugar diabetes just like us? Surprising and shocking, right? For those of you who did not know, cats including the Russian blues can suffer from diabetes just like humans.

Diabetes is caused due to the lack of insulin. The main function of insulin is to carry the glucose into the bloodstream to the cells where it is converted to energy. In the absence of insulin, the glucose builds up in blood and urine.

Similarly, water is also drawn into the urine with glucose causing an increment of urination. Hence, to replenish the lost water in the body, the cat has an increment of thirst causing it to drink an excessive amount of water than usual.

This disease can be diagnosed by blood tests and urine tests. Besides, the treatment of diabetes for cats involves providing insulin and changes in diet. Diabetes in cats usually occurs mostly in the overweighted cats.

Hepatic Lipidosis

Cats having Hepatic lipidosis suffer from increased thirst, lethargy, loss of weight, loss of appetite, jaundice, and swollen tummy. Hepatic lipidosis is a type of liver disease that is common in cats.

This disease is most common in obese cats and is caused due to the excessive accumulation of fat in the liver due to poor diet. Diagnosis can be done through a blood test and even biopsy if possible. Whereas its treatment involves aggressive feeding of a diet consisting of more liquid.


Pyometra is a womb infection, which usually occurs in female cats that have not to been neutered. The symptoms of this disease are thirst, fever, lack of appetite, vulval discharge, and vomiting. So to avoid this disease you should neuter your Russian blue when she crosses her age to seniority.


Dehydration has a wide range of causes in cats, apart from the above-listed causes. The following are some other causes of dehydration and further cause of your Russian blue cat’s excessive thirst for drinking water:

Dry Or Salty Food

Russian blues along with other breeds of cats do not drink water daily, because as per their origins they are desert animals. So, if they have a daily diet of very dry and salty food they do need to drink a larger volume of water to avoid hydration. Therefore, you should maintain their diet properly.

Blood Loss

The blood vessels rupture due to any source causing blood loss, but the blood vessels cloth over time. Your cat drinks extensively to maintain their blood pressure during the time of recovery.

Over Heating

If your Russian blue is active and playful their body can overheat from hyper activities causing probable dehydration. Your cat instinctively drinks water extensively to avoid dehydration. Another, cause of overheating is very hot weather. And as a result, your cat again drinks more than the usual volume of water.

What Should You Do If Your Russian Blue Cat Is Drinking A Lot?

When Russian blue is drinking a lot of water, then first you should try to break down the cause to simpler levels like environmental level or activity. Has the weather become too hot? Has your cat been playful recently? Is the food too dry or too salty?

If you are clear about the above-mentions not being the cause for making your Russian blue cat excessively thirsty, then you have to analyze their behavior or any symptoms related to the health of the mentioned issues.

I recommend you contact your veterinarian immediately after confirming any of the symptoms or even if you are confused regarding the cause of your cat’s drinking behavior.

A checkup with the vet will clear any doubts regarding the behavior as well as the current health condition of your furry friend. Because as sooner the start of the treatment the greater chance of positive outcomes of the problem.
