<human>: For the past two months we've been smelling some really rank shit in the living room. I found the smell kept coming from the floor around the couch so I kept using Nature's Miracle. That stuff works great everywhere else. But not here.

So one day my dad complains about the smell, again (of course takes no initiative to look, just says it smells, thanks Dad). So I say enough it enough. I flip over the couch a-... holy shit, the entire bottom on the couch. I cleaned the top already so I thought it was gone.

Why does he do it though? Is it a dominance issue (my dad spends 8:30PM-2AM working and watching TV on the couch, is the pee old? Our house has been smelling for like 5 years but it's especially been bad now)? He doesn't pee *anywhere* else inside the house, just in his litterbox outside.

:( Either some sort of repellent or something.

Can you give me the gist of the text in a nutshell?
<bot>: Cat destroyed a really fucking expensive couch (shows what happens when I spend good money with a cat in the house), any repellents or tips on how to avoid this?
