There can be many types of cat odor, and each one will have a different cause and require a different solution. In general, there are three main categories of cat odor: urine, and feces.
Urine: Cat urine is the most common type of odor, and it’s caused by peeing on furniture, walls, or other surfaces. To get rid of this smell, you’ll first need to soak the area in water for several hours. Then add some enzyme cleaner (such as Mr. Clean) to the water and scrub the surface with a brush. Finally, rinse off the area with fresh water.
Feces: Feces are also a common source of cat odor. To get rid of this smell, you’ll first need to clean the area where the feces was deposited. Fill a bucket with warm water and add some chlorine bleach. Soak up all the feces with a cloth and then toss it in the bucket. Let the area dry before cleaning it with enzymatic cleaner (like Mr. Clean). Finally, rinse off the area with fresh water.
