  • Size: Small kittens take fewer fluids compared to big ones.
  • Activity level: A more active kitten will naturally require more liquid to stay hydrated.

Potential Reasons for Increased Thirst

If your kitten is drinking more water than usual it is the 1st sign that he/she covering up illness. Some common reasons for increased thirst in kittens include:

Kidney Disease

Chronic kidney disease is typical for old cats but it can also occur in baby cats (kittens). Chronic kidney disease causes the kidneys to lose their ability of filtering toxins and waste products from the blood stream. Consequently, body attempts at driving out these substances through increase of urine production which in turn leads to increased thirst. The other signs include loss of weight, loss of appetite, vomiting and dull coat. Early spot on diagnosis with treatment are crucial in managing chronic renal disease emphasizing the need for regular veterinary check-ups.


Another medical condition, which could result into increased thirst among kittens, is diabetes mellitus. Feline diabetes develops due to inadequate insulin release or delayed response to insulin just like humans have. Kittens require insulin to maintain blood sugar levels within normal range because whenever glucose content increases there tends be frequent urination hence an increased need for water.

Liver Disease

Liver disease can contribute a lot to increased water consumption although it’s less common among kitties as compared with older cats. It can be hard to trace until they are at an advanced stage for kittens too. Symptoms associated with liver diseases vary but one of the most prominent symptoms relating to liver disease is increased thirst caused by low liver function. Others include laziness, jaundice, vomiting and loss of weight.


Although it seems counterintuitive, dehydration can also lead to higher water intake. If your kitten has become dehydrated through vomiting or diarrhea then he will naturally try replacing some liquid by taking more fluids into his/her body . It’s important that you watch closely how much water your young pet consumes during this time as this may easily result in very serious health issues.

Low-grade fever

Because of an increased temperature, lower-grade fever also causes excessive water drinking to cool down body fluids. If your kitten is showing signs such as a warm or dry nose, sluggishness and loss of appetite in addition to excessive thirst it’s better to reach out to your vet.


Hyperthyroidism is another disease that can lead to increased thirst in kittens due to the overactive thyroid gland. The hyper metabolic state associated with hyperthyroidism forces the body to process fluids more quickly resulting in greater production of urine thus leading them to require more water. While this condition primarily affects older cats, it may still trouble young ones as well. In addition to polydipsia and polyuria, clinical signs include weight loss, increased appetite and activity.

High-Protein Diet

While high-protein diets are beneficial for growth & development in cats, they can cause an increase in water intake too. Dry food contains more protein and less moisture than wet types as mentioned above earlier. The body tries to make up for the absence of fluids in their diet, which causes an imbalance that leads to increased thirst.

Medication Side Effects

Increased water intake can also be due to few medications prescribed for kittens. If your kitten is on any medication, you need to watch out how much water it drinks because if there is a change in this habit, you should ask your vet’s opinion on this matter.


Pyometra is a uterine infection that can make kittens want to drink more. Bacteria entering the uterus while in heat and causing inflammation cause this. In response, the body produces extra fluids to help combat the infection, which results in increased water intake. Moreover, other symptoms may include pyrexia, prostration, reduced appetite and discharge of pus in the vagina. In case it remains untreated, immediate medical attention is always essential for pyometra as it can turn out into a fatal illness.

Psychological Factors

Finally, one should not overlook emotional as well as psychological factors responsible for extreme thirst among young cats. When stressed or anxious, they tend to drink more water to overcome such conditions. Furthermore, bored kittens might increase their intake as an alternative way of engaging themselves through play if they lack any form of stimulation or interaction around them. If your kitten has recently been exposed to different surrounding or routine changes, this might bring about stress hence making them take excess water.
