Excessive Thirst in Cats

Cat Care

About two-third of the total number of cats are older ones, i.e., above eight years old or older than that. Owners of these senior felines, should be extra careful and aware of all the things that surround their cat’s health. As far as cats are concerned, they need constant medical attention and regular checkups.

Causes of Increased Thirst in Cats

Cats are subject to be affected with several similar diseases that are observed among human beings, especially when the cat grows older. Common human diseases like diabetes, heart diseases, kidney diseases and cancer are some of them. These are ‘senior feline diseases’ meaning, they probably catch the elder cats than the younger ones. Several of these diseases can cause extreme thirst in cats.

Feline Diabetes Mellitus

Just like the types seen in human beings, there are two types of feline diabetes – type 1 and type 2. Type 1 diabetes is caused by lack of insulin and insufficient production of insulin, while type 2 is caused when the body cells are unable to utilize the present amount of insulin. It is true that diabetes can strike cats at any age, but, older cats are more prone to the feline diabetes mellitus.

Extreme thirst in cats


  • Vomiting
  • Loss of appetite
  • Loss of weight
  • Poor fur conditions
  • Breathing problems
  • Weakness
  • Dehydration and excessive thirst

A veterinarian should be consulted, if the above symptoms are noticed so that the right medical treatment can be started.

Fatty Liver Disease

Fatty liver disease, also known as hepatic lipidosis, is a condition that is caused when there is a sudden accumulation of fat cells inside the liver, that the body system of the cats fail to utilize. The exact cause of this is not known, but, the disease can be diagnosed by performing a liver biopsy.


  • Sudden loss of appetite or weight loss
  • Excessive thirst
  • Listlessness
  • Vomiting
  • Swelling of abdomen

For proper diagnosis, it is necessary to consult a vet.

Feline Chronic Renal Failure

There is a very minute difference between acute renal failure and chronic renal failure. Chronic renal failure is the most common cause for deaths of senior felines. It causes an irreversible and gradual damage of the kidney along with hampering important functions of the kidney.


  • Weight loss
  • Loss of appetite
  • Difficulty in urinating
  • Vomiting
  • Poor condition of coat

There are several ways by which the chronic renal failure is treated. Some of them are:

Providing cats with subcutaneous fluids

Adequate and appropriate cat food

Appetite stimulants and medication

Other Reasons
  • Hyperthyroidism (overactive thyroid glands)
  • Polyuria (frequent urination)
  • Polydipsia (excessive drinking)
  • Feline hypertension (high blood pressure)

Any significant change in the cat behavior must not be overlooked as it can be the start of a cat’s illness. This is very important as far as the pet’s health is concerned. Proper treatment actually depends on the ‘root cause’ analysis to find out the reason why cats crave for water. Every particular symptom must be treated individually. This will make sure that the cat recovers, as soon as possible and has a healthy life ahead. For proper diagnosis and timely treatment, make sure you consult a veterinarian

Hi, I'm Jess and this is Nala.

I've loved cats since I was a child and over the years I became obsessed with them. I love all animals and pets, but I have studied cats with special passion. I’ve spent most of my life trying to understand them and why they are the best companions, if they ‘allow’ you to be their friend.

I put this blog together with the aim of sharing things about cats that interest me and that can help you to understand your own…

Thanks for stopping by, and I hope you find something to interest you along the way.
