That's hard to believe. Maybe the dog people are just out playing fetch or something fun instead of emptying the cat s^^t box. By the way if you have cats you might not know this but, yes, your house really does smell like cat feces and urine, Just thought you'd like to know.
We have three house cats and our house doesn't smell like cat feces. Some people don't even notice we have cats until we tell them. You just have to actually scoop out the litter box like you're supposed to. Then it has no smell.
