If you have noticed cat hydration becoming a hot topic lately, you’re not imagining it! More and more research (and more real life experiences from cat parents) are highlighting just how important hydration is for a cat’s overall health.
At the same time, hydration can feel frustrating. Cats don’t always act thirsty, they often ignore water bowls, and it can feel like you’re doing everything “right” with little visible payoff. If that sounds familiar, you’re not alone.
Hydration is not a quick fix, it’s a long game. And like most things in pet care, small consistent changes matter more than perfection.
Why is Hydration Important for Cats?
Water plays a huge role in nearly every system in your cat’s body. Proper hydration supports:
- Body temperature regulation
- Digestion
- Delivery of oxygen and nutrients to organs
- Electrolyte balance
- Joint health
When cats don’t get enough water, their bodies have to work harder to compensate, which can take a toll over time.
Why Don’t Cats Drink Enough Water?
Cats are natural desert dwellers. Their ancestors evolved in environments where water was scarce, so cats developed a low thirst drive as a means of survival.
Because of this, many cats aren’t naturally motivated to drink large amounts of water, even when their bodies need it. In the wild, much of a cat’s hydration came from prey. In modern homes, especially those relying heavily on dry food, that natural moisture source is often missing.
Cats are clean animals. They often won’t drink water if it is too close to food or their litter box because they see this as contaminated. The same goes for still water. In the wild, still water is a breeding ground for bacteria, so cats will avoid it. Running water is a signal of freshness and that it is safe to drink.
In multi-cat households, sometimes one cat will “claim” a water source and deter other cats from using it. Cats can develop a preference for certain bowls or fountains so it is helpful to have a variety of options to minimize competition and ensure everyone has water.
How Much Water Do Cats Need Each Day?
A commonly cited guideline is that cats need about 4 ounces of water per 5 pounds of lean body weight per day (Cornell).
That means an average 10 pound cat needs roughly 1 cup of water daily. This total includes water consumed through food, not just what they drink from a bowl or fountain!
This can be surprising, especially if your cat rarely drinks from their water dish, and it helps explain why hydration deserves extra attention.
What Happens If a Cat Is Dehydrated?
Chronic dehydration in cats can contribute to serious health concerns, including:
- Decreased circulation
- Difficulty regulating body temperature
- Increased likelihood of urinary stones and kidney issues
- Neurological dysfunction
- Cardiac Issues
- Multi-organ dysfunction
These are reasons why hydration is such a frequent topic in veterinary medicine and preventative cat care.
Signs and Symptoms of Dehydration in Cats
Some signs of dehydration can subtle, especially early on. Common signs and symptoms include:
- Lethargy
- Decreased appetite
- Weakness
- Dry mucous membranes
- Sunken eyes
- Loss of skin elasticity
If you notice any of these signs, especially more than one at a time, it’s important to reach out to your veterinarian.
How to Get a Cat to Drink More Water
There is no “one size fits all” solution, but combining small strategies often work best.
Feed Wet Food to Increase Hydration
Wet food can contain up to 80% water, making it one of the easiest ways to support hydration.
Keep Water Clean and Easily Accessible
Cats are sensitive to taste and smell. Fresh, clean water matters. It may also be helpful to provide multiple water stations around the home.
Try a Cat Water Fountain
Many cats prefer moving water because it signals freshness. A fountain can encourage more frequent drinking for some cats.
Add Water or Broth to Food
Adding small amounts of water or cat-safe, low-sodium broth to meals can increase daily water intake.
Use Wide, Shallow Bowls
Some cats dislike bowls that touch their whiskers, as this can produce whisker fatigue. Wide, shallow dishes can make drinking water more comfortable.
Hydration is a Long Term Part of Cat Care
Hydration doesn’t usually change overnight. It improves gradually through routine, consistency, and paying attention to what works best for your cat.
This post isn’t meant to be a rule book on hydration, it is a guide. Every cat and household is different. The goal is to reduce the mental load and create systems that support your cat’s health over time.
If you miss a day, forget to refresh water, or feel behind, that’s okay. Progress matters more than perfection.
