I have four cats (yes I know)...and one of those is a part-time problem child. If there is anything I hate..its cat urine! That must be what Hell smells like. Anyway...this stuff is wonderful. It does not have a strong perfumy smell at all yet it works wonders. Actually eliminates, does not cover up (as if that's possible). When you smell this stuff, you think..there's no way its going to work as there is no strong smell at all cause we are programmed and used to the alternative, which never worked anyway. Well this does. I only wish it wasn't so pricey.
