How To Get Cat Pee Out Of a Mattress: Step‑by‑Step FAQ Guide

If you’re searching for “How To Get Cat Pee Out Of a Mattress,” you’re likely dealing with a fresh accident, a lingering smell, or a dried stain you just discovered. This guide walks you through exactly what to do, what to avoid, and how to reduce odors so your mattress is usable again.

Why Is Cat Urine So Hard To Remove From a Mattress?

Cat urine is concentrated and contains:

  • Urea and uric acid, which can leave a strong ammonia-like smell
  • Salts and crystals that can bind to mattress fibers
  • Bacteria, which can produce lingering odors over time

On a mattress, liquid sinks down into the foam or padding, so surface cleaning alone often isn’t enough. That’s why acting quickly and using the right method matters.

What Should I Do First When My Cat Pees on the Mattress?

1. Act quickly and blot, don’t rub

  1. Strip all bedding immediately.
  2. Use clean, absorbent towels or paper towels to blot the area.
  3. Press down firmly to soak up as much liquid as possible.
  4. Do not rub, as this can push urine deeper into the mattress.

2. Avoid common mistakes

  • ❌ Do not use a steam cleaner directly on cat urine stains. Heat can set odors.
  • ❌ Do not pour harsh chemicals into the mattress; they may damage materials and still leave odor behind.
  • ❌ Do not leave the area wet for hours; this can encourage more odor and possible discoloration.

How To Get Cat Pee Out Of a Mattress: A Simple At‑Home Method

This basic approach can help with fresh and many dried stains.

Step 1: Blot thoroughly

Continue blotting until towels are coming away only slightly damp. The less urine left, the easier the rest of the process will be.

Step 2: Apply a gentle cleaning solution

Mix a simple solution:

  • 1 part white vinegar
  • 1–2 parts cool water

Pour a small amount over the affected area—enough to wet it, but not soak the entire mattress. The vinegar helps neutralize odor and dilute existing urine.

Blot again to remove excess moisture.

Step 3: Use an enzyme-based cleaner (if available)

For many people, an enzyme-based cleaner formulated for pet urine is helpful because:

  • It is designed to break down urine components
  • It can help with both stain and odor

Follow the label instructions and allow enough soak time so the cleaner can reach into the mattress layers. Then blot up as directed and allow to dry completely.

Step 4: Deodorize with baking soda

Once the mattress is damp, not wet, sprinkle a generous layer of baking soda over the area. This helps absorb both:

  • Remaining moisture
  • Some surface-level odor

Leave it for several hours or overnight, if possible. Then vacuum the baking soda thoroughly.

How Do I Dry the Mattress Properly?

A mattress that stays damp can hold onto smells longer.

  • Increase airflow with open windows and a fan.
  • If possible, stand the mattress upright in a safe, ventilated area.
  • Allow plenty of time; thicker mattresses can take a day or more to dry fully.

Avoid placing a mattress in direct harsh sun or near high heat sources for long periods, as this can sometimes affect materials or covers.

What If the Cat Pee Stain Is Old or Already Dried?

Dried stains may require repeating the process:

  1. Lightly mist the area with water to re-dampen the stain (not soaking).
  2. Apply the vinegar solution.
  3. Blot and then use an enzyme-based cleaner if you have one.
  4. Finish with baking soda and thorough drying.

Old urine may not disappear completely in one round. Some people find that several treatments help reduce the smell more effectively over time.

Is It Safe To Sleep on the Mattress After Cleaning?

In general:

  • The mattress should be completely dry before you sleep on it again.
  • Make sure there is no strong chemical smell remaining from cleaners.
  • You can use a clean, washable mattress protector once the mattress is dry and aired out to help shield it from future accidents.

If any area still feels damp or has a strong odor, allow additional drying and ventilation time.

How Can I Prevent Future Cat Pee Accidents on the Mattress?

While behavior issues are outside the scope of mattress care, you can at least protect the mattress itself:

  • Use a water-resistant or waterproof mattress protector that fully covers the sleeping surface.
  • Wash bedding promptly if accidents happen.
  • Keep spare protectors or covers on hand so you can change them quickly if needed.

A good protector can make any future cleanup much easier and limit how deeply liquid can soak into the mattress.
