 Hi, I'm Ty Pennington, and this is another one of Ty's Tips. So, floors take their share of abuse. Kicked, scuffed, spilled on, and yeah, sorry to say it, peed on. Look, dogs are man's best friend, and cats, well, I'm sure they've got friends somewhere. But when it comes to potty training, let's just say that very few pets are always perfect. Thing is, those pet stains can be a problem for you because, well, they smell. And they can be a problem for resale because they're ugly. So take care of them now.
