How Much Water Do Cats & Dogs Need Daily?

Many pet owners wonder how much water their cats and dogs should drink each day. Proper hydration is essential for digestion, kidney health, energy levels, and overall well-being.

How Much Water Do Cats Need?

On average, cats need about 3.5–4.5 ounces of water per 5 pounds of body weight per day.
For example, a 10-pound cat should drink around 7–9 ounces of water daily.

Cats that eat mostly dry food often don’t get enough moisture from their diet, which increases the risk of dehydration and urinary issues.

How Much Water Do Dogs Need?

Dogs generally need about 1 ounce of water per pound of body weight per day.
A 30-pound dog, for instance, should drink roughly 30 ounces of water daily.

Active dogs, puppies, nursing dogs, or dogs in warm climates may need even more water.

Signs Your Pet May Not Be Drinking Enough Water

Some common signs of dehydration include:

  • Low energy or lethargy

  • Dry gums or nose

  • Dark yellow urine

  • Less frequent urination

  • Loss of appetite

If you notice these signs, increasing water intake is important.

Why Many Pets Don’t Drink Enough

Many cats and dogs avoid drinking from still water bowls. Stagnant water can smell unpleasant, collect dust and hair, and lose freshness quickly. Cats, in particular, are naturally attracted to moving water, which they associate with cleanliness and safety.

A Simple Way to Encourage Better Hydration

Providing fresh, flowing water can naturally encourage pets to drink more throughout the day. Many pet owners find that switching from a regular bowl to a water fountain makes a noticeable difference in their pet’s drinking habits.
