How To Get Smell Of Cat Pee Out Of Mattress: Simple Steps That Work

If you’re searching for “How To Get Smell Of Cat Pee Out Of Mattress,” you’re likely dealing with a strong, lingering odor that doesn’t seem to go away. Cat urine can be stubborn, but with the right approach you can remove both the stain and the smell without damaging your mattress.

Below are clear, FAQ-style answers to the most common questions about cleaning cat pee from a mattress.

Why does cat pee smell so strong in a mattress?

Cat urine has a high concentration of ammonia and other compounds that create a strong, sharp odor. When it soaks into a mattress:

  • It can spread through the layers of foam or padding
  • It may reactivate and smell stronger when the area becomes warm or humid
  • If not cleaned properly, the smell can linger and even encourage repeat accidents

That’s why knowing how to get smell of cat pee out of mattress quickly and thoroughly is important.

What should I do first when my cat pees on the mattress?

Act as soon as you notice it. Fresh urine is much easier to remove than a dried, set-in stain.

  1. Blot, don’t scrub.
    Use clean, absorbent towels or paper towels to press down firmly and soak up as much moisture as possible.

  2. Avoid hot water or steam.
    Heat can set the stain and odor deeper into the mattress material.

  3. Identify how deep the stain is.
    If the spot is large or has been there for a while, you may need to repeat cleaning steps multiple times.

What’s the best way to remove the cat pee smell from a mattress?

A common and effective method uses household ingredients:

Step-by-step cleaning process

  1. Blot the area thoroughly
    Keep pressing with dry towels until they come away only slightly damp.

  2. Apply a vinegar solution

    • Mix white vinegar and cool water (about 1:1).
    • Lightly spray or pour just enough to dampen the stained area.
    • Let it sit for 10–15 minutes, then blot again.
      Vinegar helps neutralize odors and break down urine residues.

  3. Use baking soda to absorb odors

    • Sprinkle a generous layer of baking soda over the damp area.
    • Gently press it in with your hand.
    • Leave it on the mattress for several hours or overnight so it can absorb moisture and smell.

  4. Vacuum thoroughly

    • Once dry, vacuum up all the baking soda using an upholstery attachment if available.
    • Check the smell. Repeat the process if needed for stubborn odors.

This basic method is often enough to tackle most fresh and mild cat urine smells.

What if the cat pee smell still won’t go away?

Sometimes, especially with older stains, the smell is more persistent.

Try an enzymatic cleaner

Many people find enzyme-based cleaners helpful for breaking down urine compounds that cause odor. When using one:

  • Spot-test a hidden area of the mattress fabric first
  • Follow the label instructions carefully
  • Allow plenty of drying time, as enzymatic action often continues as it dries

If you use an enzymatic cleaner, avoid immediately covering the mattress with bedding. Airflow helps reduce both moisture and lingering smells.

Can I use bleach or harsh chemicals on my mattress?

It’s generally not recommended to use bleach or strong chemicals on a mattress because:

  • They can damage fabrics and foams
  • Strong fumes can be unpleasant in a sleeping environment
  • Discoloration or residue might remain on the surface

Gentler options like vinegar, baking soda, and mild cleaners are usually safer for mattress materials.

How do I dry the mattress after cleaning?

Drying is a key part of how to get smell of cat pee out of mattress effectively.

  • Increase airflow with a fan pointed at the area
  • Open windows if possible
  • If you have one, use a cool or low-heat setting on a hairdryer, keeping it moving to avoid overheating any spot

Make sure the mattress is completely dry before putting sheets or a mattress protector back on. Trapped moisture can make odors return.

How can I prevent future cat pee smells in my mattress?

While accidents happen, a few steps can reduce the risk of recurring problems:

  • Use a waterproof mattress protector to keep liquids from soaking into the mattress
  • Clean accidents as soon as you notice them
  • Wash all bedding and any nearby fabrics that may have been splashed
  • Keep the sleeping area calm and consistent for your cat, as stress can sometimes contribute to accidents
