How do I clean the soiled area?

Whether a genuine accident or not, once the cat has urinated or defecated at a particular location its sensitive nose will encourage it to use that place as a regular toilet.

The best way to break the habit is to keep the cat away from the area as long as possible, remove any smell that the cat can detect and maybe change the geography of the location by using pieces of furniture to block access.

Wash the area with a 10% solution of biological or enzymatic washing powder and then rinse with cold water and allow the area to dry thoroughly.

This method works best when the amount of liquid used is minimal to avoid over-saturating, particularly when cleaning carpet.

Once the area is dry, the final step of the cleaning process is to spray lightly with surgical spirit (using a plant mister), scrub gently and leave to evaporate.

You may want to try a small area first on delicate fabrics.

Commercially produced enzymatic cleaners are also available specifically for the purpose of removing the stain and odour of cat urine and faeces.
Carpet is extremely absorbent and urine often penetrates the full thickness of the carpet to the flooring underneath.

If the area is badly soiled with urine over a long period it may be necessary to cut out the section of carpet and underlay and treat the concrete or floorboards underneath before replacing.
