Why Is My Cat Not Using the Litter Box?

When your cat stops using the litter box, it’s essential to approach the issue with patience and understanding. Cats are creatures of habit, and any disruption to their routine can cause stress-related behaviors — including inappropriate elimination.

Here are some common reasons why your cat may be avoiding the litter box:

1. Medical Issues

Health problems are one of the most frequent causes. Conditions such as:

• Urinary tract infections (UTIs)
• Bladder stones
• Kidney disease
• Diabetes
• Constipation or diarrhea

These can all lead to discomfort or pain when using the litter box, causing your cat to associate it with negative experiences. A vet visit should be your first step if your cat suddenly stops using the litter box.

2. Litter Box Cleanliness

Cats are fastidious animals. If the litter box is dirty, smelly, or not scooped regularly, your cat may choose to go elsewhere. Make sure to:

• Scoop at least once daily
• Wash the box weekly with mild soap and water
• Replace litter as needed

3. Litter Type or Scent

Some cats are picky about the texture or scent of their litter. If you’ve recently changed brands or types, your cat may not approve. Try:

• Unscented clumping litter
• Gradually mixing new litter with the old one
• Avoiding strong fragrances

4. Location of the Litter Box

Privacy and accessibility matter. A litter box in a noisy laundry room or near a dog’s bed might not feel safe. Ensure:

• The box is in a quiet, low-traffic area
• It’s easily accessible, especially for older cats
• You have one box per cat, plus one extra

5. Stress and Environmental Changes

Cats are sensitive to change. Moving, new pets, a baby, or even new furniture can cause anxiety. Stress may lead to behavioral issues like avoiding the litter box. Use calming pheromone diffusers, maintain routines, and give your cat plenty of attention.

How to Get Your Cat to Use the Litter Box Again

Now that you’ve identified possible causes, here’s a step-by-step plan to help your cat return to proper litter box habits.

Step 1: Rule Out Medical Problems

Schedule a vet check-up to eliminate any underlying health issues. This is crucial, especially if your cat is showing other signs like straining, crying while urinating, or blood in urine.

Step 2: Clean Soiled Areas Thoroughly

Use an enzymatic cleaner to remove odors from areas where your cat has urinated or defecated. Regular cleaners may not fully eliminate the smell, encouraging your cat to return to the same spot.

When cleaning soiled areas, it’s crucial to use an enzymatic formula like the Rocco & Roxie Stain & Odor Eliminator. This professional-strength spray penetrates deep to eliminate urine odors at the source—preventing repeat accidents and making your home smell fresh again.

Step 3: Reevaluate the Litter Box Setup

• Number of boxes: One per cat, plus one extra
• Box size: Large enough for your cat to turn around comfortably
• Box type: Some cats prefer open boxes; others like covered ones
• Litter depth: About 2–3 inches is ideal

Try different combinations to see what your cat prefers. Some trial and error may be necessary.

Choosing the right litter box makes a huge difference. The PetFusion Large Litter Box features high walls for splash control, an open design for easy access, and a spacious interior that gives cats the room they need to feel comfortable—especially for large or senior cats.

Step 4: Reduce Stress

If your cat’s behavior coincides with a life change, help them adjust:

• • Use Feliway or similar calming diffusers
  • Provide vertical spaces like cat trees or shelves
  • Stick to a consistent feeding and playtime schedule

To help reduce stress and restore calm, consider using the Feliway Classic Diffuser. Vet-recommended and clinically proven, this pheromone-based solution mimics natural calming scents to help cats feel safe and comfortable—especially during major life changes or anxiety-inducing moments.

Step 5: Retrain Using Positive Reinforcement

Encourage your cat to use the litter box by:

• Gently placing them in the box after meals or naps
• Rewarding with treats or praise when they use it
• Never punishing them for accidents — this increases fear and stress

Step 6: Block Off Problem Areas

If your cat has chosen a specific spot to go outside the box:

• Use furniture or plastic mats to block access
• Place a litter box temporarily in that spot, then gradually move it

When to Seek Professional Help

If you’ve tried all the above steps and your cat still refuses to use the litter box, it may be time to consult a feline behaviorist. These professionals can help identify more subtle issues and create a tailored behavior modification plan.
