I have a male and female cat. The female cat is more likely to make a mess in the house than the male. I think all cats have a natural instinct to prefer to use the litter box since it mimics most closely what they would find outside in the wild (dirt). You just have to make sure to clean it well between uses as cats are sensitive to bad smells and will not want to use a smelly litter box. If a cat pees on carpet, not to worry, just get this. Soak carpet liberally with this stuff, rub it in, and poof the smell and stain are gone for good. It is a miracle worker!!! It works for removing other stains as well.
