Sick Cat Won't Drink Water?

Medically Reviewed by Dr. Sarah Jenkins, DVM, Feline Internal Medicine Specialist

Introduction

Water is essential for every living creature, and cats are no exception. When your cat is sick and refuses to drink, it can quickly become a serious concern. Dehydration in cats can develop rapidly and lead to dangerous complications. This article explores practical strategies to encourage your sick cat to drink and helps you understand when professional help is necessary.

Why Water Intake Matters for Cats

Cats have relatively low thirst drives compared to other animals, a trait inherited from their desert-dwelling ancestors. In the wild, cats obtained most of their moisture from prey. Domestic cats eating primarily dry food may not drink enough to compensate. When a cat is ill, this natural tendency to under-drink becomes even more problematic.

Signs that your cat may be dehydrated include:

Dry, sticky gums

Loss of skin elasticity

Sunken eyes

Lethargy and weakness

Decreased urination

Constipation

Common Reasons a Sick Cat Won't Drink

Understanding why your cat refuses water can help you address the problem more effectively:

Nausea: Illness often makes cats feel queasy, suppressing their drive to drink or eat.

Pain: Dental problems, injuries, or post-surgical discomfort can make drinking painful.

Stress: Being unwell stressful, and changes to their environment can worsen this.

Medication side effects: Some medications can cause dry mouth or nausea.

Weakness: Severely sick cats may be too weak to walk to their water bowl.

Practical Strategies to Encourage Drinking

1. Make Water More Appealing

Offer fresh, clean water in a clean bowl—changed at least twice daily

Try different bowl materials (ceramic, stainless steel, glass) as some cats have preferences

Ensure water is at room temperature or slightly cool, not too cold

2. Try Running Water

Many cats are naturally attracted to moving water. Consider:

A cat water fountain (circulating water keeps it fresh and appealing)

A dripping faucet (if your cat shows interest)

Adding ice cubes to their bowl for gentle movement

3. Multiple Water Stations

Place water bowls throughout your home in different locations:

Away from food bowls and litter boxes

In quiet areas where your cat feels safe

Near places where your cat rests frequently

4. Enhance Water Flavor Safely

Add cat-safe flavor enhancers to water:

A small amount of low-sodium chicken broth (no onion or garlic)

A splash of water from canned tuna

Pedialyte (unflavored) in very small amounts—always consult your vet first

5. Offer Hydrating Foods

Wet food and hydrating treats can supplement water intake:

Canned wet food has high moisture content (70-80%)

Bone broth (onion and garlic-free) as a supplement

Ice cubes made from low-sodium broth as treats

6. Assist with Syringe Feeding

For severely dehydrated cats, you may offer water carefully:

Use a clean syringe (without needle)

Offer small amounts frequently rather than large amounts at once

Never force water into a cat's mouth—this can cause aspiration

7. Keep the Bowl Near Your Cat

If your cat is too weak to move, bring water to them:

Place a shallow dish beside their bed

Gently touch the water surface to show them it's there

Stay calm and patient during the process

8. Address Underlying Issues

Sometimes helping your cat drink means treating the root cause:

Manage nausea with appropriate care

Ensure any dental pain is addressed

Reduce environmental stressors

Follow your vet's guidance on medication timing

When to Seek Veterinary Care

Contact your veterinarian immediately if your cat:

Has not drunk any water for more than 24 hours

Shows signs of severe dehydration

Is vomiting and unable to keep water down

Appears extremely weak or collapsed

Has underlying health conditions (diabetes, kidney disease)

Professional veterinary care may include subcutaneous or intravenous fluid administration to rapidly and safely rehydrate your cat.

Long-Term Prevention

Once your cat recovers, consider these strategies to prevent future dehydration:

Feed wet food as part of their regular diet
Provide multiple clean water sources
Consider a water fountain for cats who prefer running water
Monitor daily water intake to establish what's normal for your cat
Regular veterinary check-ups to catch health issues early
