Cat Drinking a Lot of Water and Meowing – What are the Causes?

Cats have different habits when it comes to drinking water. Factors like their lifestyle, age, breed, health status, and environmental factors may affect the amounts of water your cat drinks in a day. For instance, in warmer weather, your kitty will drink more water than when the weather is cold. However, in some instances, your cat drinking a lot of water and meowing could be a sign that there is an underlying health problem.

How to tell if your cat is drinking a lot of water

Knowing the actual amount of water your cat is drinking in a day may be daunting if you do not spend the whole day in the house. Also, if you have multiple cats, it may be difficult to tell who drank what amount. 

However, there are other signs to look out for to know if your cat is drinking a lot of water:

  1. Your cat going to the cat water bowl more frequently than usual
  2. Having to refill the water bowl more often than usual
  3. Cat drinking water from unusual sources such as water faucets, and ponds.

However, most cats do this from time to time so you need not worry unless your cat is doing it frequently. Also, if your cat constantly opts to drink from other water sources, check if their water bowl is clean. Cats will not drink water from a dirty bowl. Therefore, ensure that you clean the water bowl daily and fill it with clean water.

A cat drinking a lot of water and meowing may be a sign of underlying health problems. Since cats are good at hiding what is bothering them, it is important to look out for other symptoms.

If you notice that apart from drinking a lot of water and meowing, your cat has any of the following symptoms, take them to the vet immediately.

Other symptoms that could indicate that your cat is unwell

1.Change in appetite

If you notice that your cat is eating more or less than often, contact your veterinarian. A cat with hyperthyroidism may have an increased appetite and drink a lot of water and meow excessively. Also, loss of appetite where a cat goes for long periods without food is a call for alarm.

Cats should not go without food since they may develop a fatal liver condition. Thus, take your cat the veterinarian immediately you notice changes in their appetite to rule out any health conditions.

2. Behavioral change

Sudden changes in a cat’s behavior should not be taken lightly. For example, a calm cat suddenly becoming aggressive and avoiding contact could be an indication that he is in pain.

3. Diarrhea and vomiting

A cat may get diarrhea from an upset stomach or after eating something they should not eat. However, a cat with constant diarrhea that is frequent and explosive should be taken to the veterinarian immediately. Also, cats may vomit from a stomach upset or when getting rid of hairballs.
