The carpet is so stain resistant that a Sharpie permanent marker cannot stain it; also bleach will not damage it.We also use stain guard pad with the carpet that will not allow liquids, and pet urine to penetrate into the pad or flooring below.When tenants moved out, we require them to have the carpets professionally cleaned.

Single story with concrete slab...maybe that is better although i have never had to get rid of cat urine odor out of either material.
