How To Remove Cat Pee Smell

Few things are more frustrating than smelling that one special scent your cat leaves behind when they feel like peeing outside the litter box.

Cat urine smell is pungent, awful, and, most importantly, incredibly difficult to clean for most pet parents.

Cat urine contains special compounds that give it an extremely stubborn smell that won’t go away, no matter how many times you clean the area.

So, if your cat urinated on the carpet, or developed house soiling behavior, or you are moving into a place that has urine odor problems, you are in the right place.

Continue reading to learn how to remove cat pee smell from different places in the house and clothing.

Why Cat Pee Smells So Strong

Cat urine is often said to be one of the most difficult household odors to remove, and this is for good scientific reasons.

Cats have very efficient kidneys, which allow them to concentrate their urine more than most other animals.

The stronger the urine, the greater the proportion of waste compounds in each drop. In its fresh state, urine is a solution of urea, water, salts, and other waste products.

As the urea decomposes, it produces ammonia, a sharp, pungent smell that most people are familiar with.

Over time, the uric acid present in the urine will crystallize into microscopic particles that bind extremely tightly to whatever surface they land on.

The crystals are insoluble in water, which is one of the reasons why regular cleaning is often not a solution when trying to figure out how to eliminate cat urine odor.

To make things worse, these uric acid crystals can ‘reactivate’ when exposed to water or high humidity levels.

This is why an old accident can seem like it’s gone for months, only to stink strongly of urine again on a rainy day.

As the bacteria decompose the leftover byproducts, they give off additional stinky byproducts, including sulfur-containing compounds.

Some cats naturally have stronger urine than others, particularly unneutered males, whose pee is full of extra hormones and pheromones.

How To Get Cat Urine Out of Carpet

Cat urine can be absorbed and retained in carpet fibers and padding for a long time. The longer the urine is allowed to remain, the stronger the odor.

Even when a dried stain is no longer visible to you, your cat will be able to smell it and may continue to use the area as a bathroom, resulting in multiple incidents in the same place.

For new stains:

Locate the affected area and blot up as much of the moisture as possible with a clean, absorbent cloth or paper towels.

Press down firmly to lift moisture from carpet fibers, but avoid rubbing, which may force urine deeper into the fibers.

Rinse the area with cool water, and immediately extract the moisture using a wet/dry vacuum.

Do not use a steam cleaner; heat can cause the uric acid crystals to bond to the carpet, rendering the odor permanent.

Douse the area with an enzyme cleaner, such as this one from EcoStrong, to help cat urine penetrate through the carpet and into the carpet backing and padding.

Allow the product to dwell for the recommended time, typically 10–15 minutes for new stains.

Remove moisture with blotting or additional vacuuming, and allow the area to dry completely before allowing pets back onto the carpet.

For older stains:

To properly address how to remove dried cat pee from carpet, you first need to locate the full extent of the stain by using a UV black light in a dark room.

Rinse with cool water and blot up as much moisture as possible before applying the enzyme cleaner.

Use a large amount of cleaner and let it dwell for an extended period of time. Repeat as necessary.

Allow the area to dry completely. It may take several hours. Fans and open windows will help prevent any residual moisture from reactivating the odor.

How To Get Cat Pee Smell Out of Furniture

Cat urine can be absorbed by furniture in a variety of ways, depending on the material, so the type of cleaning must be targeted to the surface.

Sealed wood, such as finished floors, baseboards, and furniture, will likely be easier to clean than porous or upholstered surfaces.

Begin by blotting up any excess moisture with a clean, absorbent towel if the accident is still wet.

Use a sponge or cloth dampened with plain water to remove any residue on the surface. Do not soak the wood, as standing water will damage the finish.

If the stain has already dried or if the smell remains, use an enzymatic cleaner that is formulated for pet urine.

These will eliminate the compounds that are causing the odor and will also prevent your cat from re-marking the area.

Apply enough of the solution to saturate the surface, allow it to set for the amount of time recommended on the container, and wipe away.

Wipe the surface again with a sponge and plain water to remove any remaining cleaner. Dry the area well with a clean cloth.

You may need to repeat this drying process several times; any moisture that remains will seep into joints or edges and can cause warping or residual odor.

While some sources suggest using hydrogen peroxide for cat pee, this is not recommended for wood

This is because it can damage the finish and is less effective than enzymatic solutions for breaking down the uric acid.

How To Remove Cat Pee Smell from Clothing

If you have clothing that has been urinated on, it is important to clean it quickly. First, rinse the affected area with cold water to remove as much urine as possible.

We recommend avoiding hot water because this can cause the odor-causing compounds to bind to the fabric.

Put the clothing in the washing machine and wash it with your regular detergent and 1 cup of baking soda or ¼ cup of vinegar. Use a cool or warm cycle, depending on the care label.

If there’s any odor left, try treating it with an enzyme cleaner designed for pet urine. You can add it to the wash or, if the product directs, use it in a presoak.

Be sure to air-dry the clothing item first. Using the dryer while the odor is still there can set it permanently. You may have to wash and treat a few times for particularly stubborn odors.

How To Remove Cat Pee Smell from a Mattress

Knowing how to clean cat urine on a mattress can be a challenge because the liquid soaks so far down into the layers.

Effective cat pee smell removal from a mattress takes time because you need to remove the odor from both the surface and the interior padding.

Use a clean, absorbent towel and blot up as much urine as possible. Press firmly to absorb moisture, but do not rub because it can smear the stain.

Apply a generous amount of enzyme-based cleaner to the stained spot, saturating it so that it can soak down into the padding.

It is usually best to pour or heavily spray so that the liquid penetrates the same depth as the urine.

Wait at least 15 minutes (or the dwell time listed on the label), and then blot the area again to dry up excess moisture.

Let the mattress dry in a well-ventilated room. Fans and open windows can help reduce the drying time.

Mattresses are thick and absorbent, so it’s likely that you’ll need to go through this process more than once. Persistence and allowing for proper drying between treatments are key.

After your mattress is thoroughly cleaned and dried, we recommend investing in a good waterproof mattress protector to shield it from future accidents.

This provides an impenetrable barrier and reduces cleanup to nothing more than stripping the bed and washing the cover.

How To Stop Cats from Peeing in House

1. Offer a litter box

Make sure it is a good size, like this one by WoofieGo, and at least one and a half times the length of your cat’s body, so they have room to move.

Scoop it daily and change the litter often. Cats will usually avoid using a dirty box, so this is one of the easiest ways to prevent the behavior.

2. Put boxes in good locations

Place them in quiet, accessible locations and keep them away from food and water bowls. Avoid tight spaces that trap odor and are potentially uncomfortable or unsafe for your cat.

3. Meet your cat’s emotional needs

Boredom, stress, or anxiety can lead to house soiling. Daily play sessions, interactive toys, and lots of affection can help keep your cat emotionally stimulated and at ease.

For persistent stress, consider using a calming pheromone diffuser in the rooms where your cat spends the most time.

4. Watch your kitty’s health

Fluctuations in urination patterns can signal illnesses such as urinary tract infections, kidney problems, or bladder stones.

Visit the vet if you observe signs of excessive urination, the presence of blood, or other alarming symptoms.

5. Odor-proof it

Spraying the area with an enzyme cleaner for cat urine will neutralize the remaining odor markers that a cat can still smell.

6. Consult a professional if necessary.

If you have tried everything and your cat is still urinating in the house, seek the advice of a qualified trainer or feline behaviorist to identify the problems and work out possible solutions.

Conclusion

The secret on how to remove cat pee smell effectively from your house and household items involves a few key steps.

As you have seen, the odor is caused by long-lasting chemicals that must be eliminated, which usually requires an enzyme-based cleaner.

You also need to find all the affected areas, apply the cleaner, and give it time to do its job. This may sometimes involve multiple applications for thicker substances.

Equally important to cleaning cat urine is finding and addressing the cause of the accident. It may be due to a medical condition, stress, territorial marking, or an issue with the litter box.
