Finding cat pee on your mattress is never fun, and it can feel like a big problem when it happens. Many pet owners face this common issue, and while it might seem tough to fix, there's actually a simple way to clean it up. According to Dr. Karen Becker, a veterinary expert at HealthyPets.com, "Cat urine has a strong ammonia smell that gets worse over time if not cleaned properly, making quick action important." The good news is that you can get your mattress clean and fresh again with the right approach, and you don't need to be an expert to do it. Let's look at how to solve this everyday pet problem and get your bed back to normal.
Fresh Urine Spreads Fast

When your cat has an accident on your mattress, you'll need to act quickly since fresh urine can spread rapidly through the layers of foam and fabric.
Cat pee contains uric acid and other compounds that begin soaking deeper immediately. For effective odor removal, we recommend quick action – blot the area thoroughly to absorb excess liquid before it can create lasting stains.

Let's explore the essential dos and don'ts when tackling cat urine on your mattress.
We'll walk through the proven steps that work best, from initial blotting to using enzyme cleaners, and highlight common mistakes to avoid during the cleaning process.
Before we get into the specific techniques and precautions, it's important to understand that quick action and proper cleaning methods will determine how successful you'll be at removing both the stain and odor.
Things to Do When Cleaning Cat Pee From a Mattress
Cleaning cat urine from a mattress requires quick action and the right combination of cleaning products to effectively remove both stains and odors.
The key is to start by absorbing as much of the urine as possible before it seeps deeper into the mattress material, then follow up with a systematic cleaning process using common household items that break down the urine compounds and neutralize lingering smells.
- Blot the area – Press firmly with paper towels or clean cloths to absorb maximum moisture without rubbing.
- Mix vinegar solution – Combine two parts cold water with one part white vinegar and a small amount of detergent.
- Apply cleaning solution – Spray the mixture generously on the affected area and let it sit for 10-15 minutes.
- Secondary blotting – Use fresh towels to absorb the cleaning solution and lifted urine.
- Apply baking soda – Cover the entire treated area with a layer of baking soda.
- Allow extended drying time – Leave the baking soda undisturbed for at least 8 hours.
- Vacuum thoroughly – Remove all dried baking soda with a vacuum cleaner.
- Use enzyme cleaner – Apply a pet-specific enzyme cleaner for stubborn odors, saturating the affected area completely.
Things to Avoid When Cleaning Cat Pee From a Mattress
When dealing with cat urine on a mattress, it's essential to understand that certain cleaning methods and products can actually worsen the situation rather than solve it.
Using the wrong approach not only risks damaging your mattress but can also make the odor more persistent and potentially encourage your cat to return to the same spot, creating a cycle of unwanted behavior that becomes increasingly difficult to break.
- Ammonia-based cleaners: These products smell similar to cat urine and may encourage your cat to mark the same spot again.
- Scrubbing motions: Aggressive scrubbing pushes urine deeper into mattress fibers and spreads the contamination.
- Bleach and harsh chemicals: These can damage mattress materials and fail to properly neutralize urine odors.
- Excessive water: Too much moisture can soak into the mattress padding, leading to mold and mildew problems.
- Incomplete drying: Leaving the mattress damp after cleaning creates an environment for bacteria growth and persistent odors.
Steps
Getting cat urine out of a mattress requires swift action and the right combination of cleaning products to eliminate both stains and odors effectively.
Cat urine can be particularly challenging to remove due to its strong ammonia content and tendency to seep deep into fabrics, but following a methodical cleaning approach can help restore your mattress to a fresh, clean state.
Step 1: Immediately blot the affected area with paper towels to absorb as much urine as possible.
Step 2: Mix two parts cold water with one part white vinegar to create a cleaning solution.
Step 3: Apply the vinegar solution generously to the stained area.
Step 4: Let the solution sit for 10-15 minutes.
Step 5: Blot the area again with clean paper towels.
Step 6: Sprinkle a generous layer of baking soda over the entire affected area.
Step 7: Allow the baking soda to sit for at least 8 hours.
Step 8: Vacuum up all the baking soda thoroughly.
Step 9: Apply an enzyme-based pet urine cleaner if stains or odors persist.
Step 10: Confirm complete drying by placing the mattress in sunlight or using a fan.
