Dealing with a cat that pees outside the cat litter box can be a real headache. It’s messy, it’s smelly, and it leaves you wondering what’s gone wrong. But before you get too frustrated, remember that your feline friend isn’t doing this out of spite. There are several reasons why this might be happening, and we’re here to help you figure it out. Let’s dive into the common causes and solutions for this perplexing issue.

Why Is Your Cat Peeing Outside the Litter Box

The 7 Possible Reasons Your Cat Is Peeing Outside the Litter Box

1. Medical Issues

Signs Your Cat Might Have a Medical Problem

  • Urinating outside of the litter box
  • Straining to urinate
  • Frequent in-and-out visits to the litter box
  • Meowing in distress
  • Passing very little or no urine
  • Blood in urine
  • Refusing to eat
  • Lethargy
  • Vomiting
  • Distended painful abdomen
  • Frequently licking the genital area

Medical issues, particularly those affecting the urinary tract, are a common reason for inappropriate urination. Conditions like feline lower urinary tract disease (FLUTD) can cause severe discomfort and even become life-threatening if untreated.

How To Solve The Problem

  • See the vet immediately: If your cat shows signs of FLUTD or urinary blockage, it’s an emergency.
  • Follow treatment plans: Ensure you adhere to all medical advice given by your vet.

2. The Box Is Dirty

Cats are clean creatures and may refuse to use a dirty litter box.

How To Solve The Problem

  • Scoop the box daily: Ideally twice a day.
  • Change the litter frequently: Ensure it’s always fresh and enough is in the box.

3. Dislikes the Litter

Some cats are picky about the type of litter used.

How To Solve The Problem

  • Experiment with different litters: Find a type your cat prefers and stick with it.
  • Use unscented, clumping litter: This is generally well-tolerated by most cats.

4. Dislikes the Litter Box

The type or location of the litter box can be a problem for some cats.

How To Solve The Problem

  • Check the box size and type: Ensure it’s large enough and try both open and closed boxes.
  • Choose a quiet location: Place the box in a calm, private area away from noisy appliances.

5. Territorial Squabbles

Cats are territorial animals. Adding a new cat to the home can trigger marking behavior.

How To Solve The Problem

  • Provide enough litter boxes: One per cat plus one extra.
  • Separate the boxes: Place them in different locations to reduce conflict.
  • Use pheromone products: These can create a calming environment.

6. Stress

Stress can cause cats to urinate outside the litter box.

Common Stressors

  • New people or pets
  • Guests or loud noises
  • Home repairs or construction
  • Stray cats outside

How To Solve The Problem

  • Identify the stressor: Try to figure out what’s causing the stress.
  • Provide a safe space: A quiet room with their essentials can help.
  • Introduce changes slowly: Whether it’s new pets or home alterations.
  • Consult your vet: For behavioral modification or medications if needed.

7. Previous Urine Smells

Cats may return to places where they’ve previously urinated.

How To Solve The Problem

  • Clean thoroughly: Use enzymatic cleaners to break down urine odors.
  • Move the litter box: Placing it where accidents occur can encourage proper use.
