I've used this product for years and the best part is that the formula is such that it takes all the smell away so the cat isn't likely to return to that spot.

Pros: Effective

Cons: none

This is a very good product with urine odor. It does need some repeated applications, however, to do the whole job.

Pros: Works well

Cons: often needs repeated apps

This stuff has saved us many (unfortunately!) a time!! Works very well with no lingering perfumey smell.

Pros: Works GREAT!

Cons: none

This product is worth what I pay for it. With multiple cats, the messes happen. This kills the smell.

Pros: Works

Cons: none

On the advice of a vet, we tried this and it does work, but it sometimes takes repeated applications.

Pros: You can get it in many stores

Cons: You need quite a bit on stubborn stains
