Hydration is Key: How to Ensure Your Cat Drinks Enough Water

As a cat owner, you know that your feline friend needs a lot of love and attention to thrive. One of the most important aspects of their health that you might overlook is their hydration.

While it might seem that your cat is not drinking as much water as they need to, the consequences of dehydration are severe. This article explores the importance of fresh drinking water for cats, how their water needs depend on their diet, and how to make sure they get enough of it.

Dehydration and its Dangers

Cats are known for being independent and self-reliant creatures, which can sometimes lead to your cat not drinking enough water. Dehydration is a common occurrence in cats and can lead to several health problems if left untreated.

These problems can range from mild to life-threatening and can be easily prevented by taking a few simple steps. The primary danger of dehydration is that it can lead to kidney failure.

The kidneys are responsible for filtering toxins from the blood and removing excess water from the body. When a cat becomes dehydrated, the kidneys cannot function properly, and toxins build up in the bloodstream, leading to renal failure.

Symptoms of dehydration include lethargy, decreased appetite, and dry, sticky gums. If your cat shows any of these signs, contact your veterinarian immediately.

Treatment of Renal Failure and Extra Fluids

If your cat has been diagnosed with renal failure, you will need to take special care to ensure that they drink enough water. Your veterinarian may recommend increasing your cat’s daily fluid intake by adding extra fluids to their diet or giving them subcutaneous injections of fluids.

While this might seem daunting, it is an easy and effective way to keep your cat hydrated and healthy. If your cat is not drinking enough water on their own, there are several things you can do to encourage them to drink more.

One of the simplest ways is to provide fresh, clean drinking water in a variety of locations around your home. This can include multiple bowls in different rooms or even a cat water fountain.

Providing wet food, like canned food, can also help increase their daily water intake.

Excessive Water Intake as a Warning Sign

While dehydration can be a serious problem, it is also essential to monitor your cat’s water intake and look out for any signs of excessive drinking. If your cat is suddenly drinking more water than usual, it can be a warning sign of an underlying health issue.

Hyperthyroidism and diabetes are two common conditions that can cause your cat to drink more water than usual. Hyperthyroidism is a condition where the thyroid gland produces too much of a hormone that regulates metabolism.

This condition can lead to an increase in your cat’s appetite and thirst, as well as weight loss. Diabetes, on the other hand, is a metabolic disorder that affects how the body uses insulin.

The result is an increase in blood glucose levels, which leads to increased urination and thirst. If you notice a sudden increase in your cat’s water intake, it is recommended that you take them to the veterinarian for a check-up.

Cats’ Natural Water Content and Prey Diet

Cats are obligate carnivores, which means that they require a diet rich in animal protein to maintain good health. In the wild, cats primarily consume prey, which has a high water content.

The average prey diet is around 67% water, which means that cats in the wild do not need to drink as much water as domestic cats. When you feed your cat a diet of dry food, they are not getting enough water.

Dry food typically has a water content of only 10%, which means that your cat needs to drink up to four times as much water to compensate. Canned food, on the other hand, has a water content of around 70-80%.

This is much closer to the natural water content of prey, and feeding your cat wet food can help increase their overall water intake.

Water Content in Dry and Canned Food

The water content in your cat’s food is essential to their health. As mentioned before, dry food has a low water content, and cats that consume this type of food are more prone to dehydration.

While it might seem that feeding your cat dry food is more convenient, it can lead to serious health problems if they do not drink enough water. Canned food is a better option as it has a much higher water content, which is closer to the natural water content in prey.

This means that cats that consume canned food are more likely to stay hydrated without having to drink excessive amounts of water. Even still, it is important to monitor your cat’s water intake, as some cats may not drink enough water on their own.

Formula for Required Daily Water Consumption

Knowing how much water your cat needs to drink each day can be confusing. Dr. Jennifer Coates, a veterinary writer, suggests a formula to help calculate your cat’s required daily water consumption.

For every pound of body weight, cats should drink around 2.5 to 3.5 ounces of water daily. For example, a 10-pound cat should drink between 25 to 35 ounces of water per day.

It is important to note that this is only a rough estimate, and your cat’s water needs may vary depending on several factors. Factors like their activity level, environment, and overall health can all affect how much water they need to drink each day.

You may need to adjust this number based on your individual cat’s needs.


Remember that water is an essential component of your cat’s overall health. Dehydration can lead to serious health problems like kidney failure, so it is crucial to monitor your cat’s water intake and make sure they are drinking enough water each day.

The natural water content in prey means that cats in the wild do not need to drink as much water. However, domestic cats that consume dry food need to drink more water to compensate.

Canned food is a better option as it has a higher water content. With a little understanding and proactive care, you can help keep your cat happy and healthy for years to come.

As a cat owner, you want to ensure that your furry friend stays healthy and happy. One of the most important ways to do this is by making sure they consume enough water each day.

Adequate water intake is essential to maintaining your cat’s health and preventing dehydration. This article provides recommendations for encouraging your cat to drink enough water.

Availability of Fresh, Clean Water

One of the simplest ways to encourage your cat to drink more water is by providing fresh, clean water in a variety of locations around your home. You can achieve this by placing multiple water bowls in different rooms or even investing in an automatic water dispenser that flows in fresh water.

Water bowls should be cleaned and refilled with fresh water daily. The water should not be stagnant since cats are naturally drawn to moving water.

Movement stimulates their curiosity and encourages them to drink more water. You can achieve this by purchasing a cat water fountain, which recirculates the water and filters it.

Signs of Dehydration and Response

Dehydration can occur in cats of any age, breed, or gender, and it can be life-threatening if left untreated. Therefore, it is essential to monitor your cat for signs of dehydration, including:


Lethargy and decreased activity

2. Panting or increased breathing rate


Dry, sticky gums or mouth

4. Sunken and/or dry-looking eyes


Poor skin elasticity

To check for dehydration, assess the skin elasticity of your cat. When you pinch their skin, it should bounce back to its normal position quickly.

If the skin takes longer to return or falls back slowly, then it is likely that your cat is dehydrated.

If you notice any of these symptoms, contact your veterinarian immediately for a consultation.

The veterinarian may recommend subcutaneous fluid therapy (an injection of fluids under the skin), which will help to rehydrate and restore your cat’s hydration levels.

Methods for Increasing Water Intake

If your cat is not drinking enough water on their own, there are several things you can do to encourage them to drink more. Here are some useful tips:


Provide wet food: The moisture and high water content in canned food can increase the overall water intake of your cat. Wet food also contains animal protein, which is essential for your cat’s health.

2. Add water to dry food: If your cat prefers dry food, add some water to it.

You can gradually increase the amount of water until they are used to eating a wetter meal. 3.

Use ice cubes: Place a few ice cubes in your cat’s water bowl to cool down the water and create a playful activity. 4.

Make water more interesting: Place a fishbowl toy in the water bowl to stimulate your cat’s curiosity and encourage them to drink more water. 5.

Try different water bowls: Try different water bowls, like ceramic, plastic, or stainless steel to provide a variety and see which one your cat prefers their water in. In conclusion, cats require adequate water intake to stay healthy.

Ensuring that your cat always has access to fresh and clean water, monitoring them for signs of dehydration, and encouraging them to drink more water are simple yet effective ways to ensure their well-being. In summary, adequate water consumption is essential to maintaining a healthy cat.

Dehydration can cause serious health problems, including kidney failure. Therefore, owners must ensure their cats always have access to fresh and clean water by placing multiple water bowls in different locations.

Signs of dehydration like lethargy, dry gums, and poor skin elasticity should not be ignored. Wet food, ice cubes, or adding water to dry food are methods to increase water intake.

Encouraging cats to drink more water by making it more interesting is effective and affordable. Remember, being attentive to a cat’s water intake can prevent serious health issues such as dehydration and keep them happy and healthy for years to come.
