cat peed in 5 corners of my new house within a month or so of moving in, despite cat door to garage and garage door being 1ft up. bought a 150$ carpet steamer and some other urine away type products. the steamer got most of the pee but i had to even replace the padding in those spots. went through three other products before this one and none worked. finally i found this and the smell is totally gone. do not expect it to work like magic, it still requires alot of prep work. the cat got ran over the day after the smell was finally gone, karma is a bitch aint it. my other two kitties doin great and still no smell now two months later
