Water plays a vital role in your cat’s overall health, yet many cat owners are surprised to learn just how little their feline companions drink on a daily basis. While it’s true that cats naturally have a lower thirst drive compared to other animals, a noticeable drop in water intake can be a warning sign. Dehydration in cats can escalate into more serious conditions affecting the kidneys, urinary tract, and general wellbeing.
If you’re in the Boston area and concerned your cat may be showing signs of dehydration or illness, MetroVet provides thorough diagnostics and hydration support tailored to feline needs.
Understanding Your Cat’s Hydration Needs
Cats descended from desert-dwelling ancestors, which means they are evolutionarily designed to extract moisture from their food. In the wild, a cat consuming prey like mice would meet most of its hydration needs through that food alone. Domestic cats, however, often eat dry kibble, which contains only about 10% moisture compared to wet food’s 70-80%. This dietary shift is a common reason cats don’t drink as much from a water bowl.
The average cat needs roughly 3.5 to 4.5 ounces of water per 5 pounds of body weight per day. If a 10-pound cat is eating mostly dry food, they should be drinking nearly a full cup of water daily. Many fall short of this amount, which may go unnoticed until symptoms of dehydration appear.
Signs Your Cat May Be Dehydrated
It can be tricky to spot dehydration in cats since they tend to hide discomfort. Common signs include sunken eyes, lethargy, dry gums, constipation, decreased skin elasticity, and reduced appetite. You might also notice more subtle behavioral changes: avoiding the water bowl, peeing less often, or showing restlessness.
A simple at-home test is the skin tent test. Gently lift the skin between your cat’s shoulder blades. If it doesn’t snap back into place quickly, your cat may be dehydrated and should be evaluated by a veterinarian.
Why Cats Avoid Their Water Bowls
Several reasons can contribute to a cat refusing to drink water. Environmental, medical, and behavioral factors can all play a role:
Water bowl placement and cleanliness
Cats are sensitive to where and how their water is offered. If the bowl is too close to the litter box or food dish, they may avoid it. Some cats dislike the smell or taste of tap water or are put off by plastic bowls that absorb odors. Dirty bowls or stale water can also be turn-offs.
Underlying health conditions
Chronic kidney disease, urinary tract infections, diabetes, and hyperthyroidism can all disrupt a cat’s water consumption. Paradoxically, some of these conditions may make them drink excessively, while others suppress their appetite and thirst altogether. If your cat has suddenly stopped drinking, a veterinary exam is necessary to rule out these serious issues.
Stress and behavioral changes
Cats are creatures of habit, and stress can significantly impact their behavior. A recent move, new pet, loud noises, or changes in routine may make a cat less inclined to drink. Some may become too anxious to approach their usual water source.
Pain or dental issues
Oral pain from dental disease can discourage drinking. Cats with inflamed gums, broken teeth, or oral ulcers might avoid water because it hurts to lap or swallow. This is especially true with cold water, which can intensify discomfort.
Encouraging Your Cat to Drink More Water
When you’re trying to improve your cat’s hydration, it’s essential to approach the issue from multiple angles. Encouraging water consumption isn’t about forcing your cat to drink but about understanding their preferences and instincts.
Switch to wet food or add moisture
Transitioning your cat to a wet food diet is one of the most effective ways to increase hydration. If a full switch isn’t possible, consider mixing water or low-sodium broth into their dry food. This not only boosts water intake but can also make meals more appealing.
Experiment with water bowl placement
Try placing several bowls throughout the house in quiet, accessible areas. Cats may prefer to drink away from their food and litter box. Observe where your cat tends to rest and place a bowl nearby. Also, avoid high-traffic zones or noisy appliances that could deter them.
Upgrade the water source
Many cats are drawn to moving water. Pet water fountains provide a continuous stream that mimics natural sources like streams or faucets. This can stimulate a cat’s interest and encourage regular drinking. Be sure to clean the fountain weekly and change filters as needed.
Change bowl material and keep it clean
Some cats are picky about the texture or smell of their bowls. Stainless steel, ceramic, or glass options tend to be better tolerated than plastic, which can hold odors and bacteria. Always rinse and refill water bowls daily to ensure freshness.
Try flavor enhancers
Unsalted broth (without onion or garlic) can be added in small amounts to water to increase palatability. There are also pet-safe water flavorings available, but consult your veterinarian before adding anything new to your cat’s routine.
When to Seek Veterinary Attention
If your cat hasn’t been drinking for more than 24 hours or is showing signs of dehydration, a veterinary evaluation is essential. The underlying cause could range from a temporary upset stomach to more serious systemic issues.

At the clinic, a veterinarian may perform bloodwork, urinalysis, and imaging to identify potential issues. Treatments may include fluid therapy, dietary adjustments, or medication depending on the diagnosis. Dehydration itself may require subcutaneous or intravenous fluids to restore balance quickly and safely.
Maintaining Long-Term Hydration Habits
Once your cat is rehydrated and any underlying issues have been addressed, the focus should shift to long-term habits that support hydration. Keep an eye on their eating and drinking behavior, especially during seasonal changes or periods of stress. Regular vet check-ups can help catch any early signs of health concerns before they become more serious.
Hydration is a cornerstone of feline health. By staying alert to changes and making small, cat-friendly adjustments to their environment, you can make a significant difference in your cat’s quality of life.
