One of the most frustrating calls we receive is from pet owners who have already had their carpets professionally steam cleaned, only to find their cat or dog keeps returning to the exact same spot.

Recently, a customer from Carnegie contacted Black Gold Carpet Cleaning with this very problem.

The Situation

The customer explained that her cat had been repeatedly urinating in the same area of carpet. Concerned about the smell and potential damage, she had already hired another carpet cleaning company to steam clean the affected area.

Unfortunately, despite the cleaning, the cat continued to return to the same spot.

This is actually a very common issue with pet urine contamination.

Why Professional Carpet Cleaning Doesn’t Always Solve Pet Urine Problems

Many people assume that if the carpet looks clean and smells better to them, the problem has been solved.

However, cat urine odour is particularly difficult to remove completely.

When urine soaks through the carpet fibres and into the underlay beneath, standard carpet cleaning may improve the appearance of the carpet but not fully eliminate the contamination underneath.

Even if humans can no longer smell the urine, a cat’s sense of smell is far more sensitive than ours. If they can still detect traces of their previous marking spot, they often continue the behaviour.

Our Advice

Rather than immediately booking another clean with us, we suggested that the customer first contact the company that had performed the original cleaning.

We recommended asking them to return and carry out a dedicated pet urine treatment before re-cleaning the affected area.

Our reasoning was simple:

If the original cleaning company could successfully resolve the issue, it would save the customer money and avoid unnecessary work.

We also explained that if the odour had penetrated deeply into the underlay, replacement of the affected underlay might ultimately be required and to ensure that the sub floor was cleaned and treated before the new underlay is installed.

The Outcome

The customer arranged for the carpet to be re-treated and cleaned.

Unfortunately, despite these additional efforts, the odour remained and the cat continued peeing on the same spot on the carpet.

At this point, the most likely cause was urine contamination trapped within the underlay beneath the carpet.

The customer decided to replace the affected section of underlay.

This is often the only permanent solution when cat urine has soaked deeply into the flooring system.

How to Stop a Cat Re-Soiling the Area After Underlay Replacement

After the underlay was replaced, the customer contacted us again with another question:

“How do I stop my cat from peeing there again?”

Fortunately, once contaminated underlay has been removed, the odour source is usually eliminated, significantly reducing the likelihood of repeat incidents.

However, we suggested several additional precautions.

1. Temporarily Cover the Area

For the first few weeks, place protective sheets or mats over the repaired section of carpet.

This prevents easy access to the area while helping break the cat’s habit of returning there.

2. Place Food and Water Bowls Nearby

Cats rarely choose to urinate where they eat.

Placing food and water bowls over the previous problem area can help discourage marking behaviour.

3. Move the Cat’s Bed to the Area

Similarly, cats generally avoid soiling places where they sleep.

Positioning their bed over the area can help create a new association with the space.

4. Consider Cat-Safe Deterrents

Some pet owners have success using plug-in diffusers or cat-safe scent deterrents designed to make certain rooms or areas less appealing.

Always choose products specifically designed for cats and follow the manufacturer’s instructions.

What If the Cat Has Another Accident?

If your cat urinates on the carpet again, quick action is critical.

Here’s what we recommend:

Step 1: Absorb As Much Urine As Possible

Use clean, absorbent towels or cloths to blot up as much moisture as possible.

Remember: Dab, don’t rub.

Rubbing can spread the contamination deeper into the carpet fibres.

Step 2: Lightly Rinse With Water

Lightly spray the affected area with water and continue blotting with a clean cloth.

This helps dilute any remaining urine residue.

Step 3: Apply an Enzyme Cleaner

Enzyme-based pet urine cleaners are available from most pet supply stores.

These products work by breaking down the organic compounds in urine that cause lingering odours.

For best results:

• The carpet should be slightly damp.
• Follow the product instructions carefully.
• Do not rinse unless directed.
• Allow the enzymes time to work naturally.

Always test any cleaning product in an inconspicuous area first to ensure it does not affect the carpet’s colour or texture.

The Key Lesson

This Carnegie case highlights an important point:

If a cat keeps returning to the same spot after carpet cleaning, the problem may not be in the carpet itself—it could be in the underlay underneath.

Until the source of the odour is completely removed, many cats (and dogs) will continue to revisit the area.

By identifying the real cause and taking steps to change the cat’s behaviour afterwards, this customer was finally able to break the cycle and protect her newly repaired carpet.

If you’re dealing with recurring pet urine problems in your home, Black Gold Carpet Cleaning can help assess whether the issue is a surface contamination problem or something deeper beneath the carpet.
