Hell, when my friends come over they never complain. One of them is allergic to cats, but not to the point where it's a HUGE issue. I dust, vacuum, wash the carpet, change the sheets, etc. before they come over because I want the place to be as comfortable as possible.

Again, I never get any remarks from them or any other friends that come over. It's always family.

I agree with others here when they say that if they have a problem with it, they can help clean. One of my biggest pet peeves is someone coming in just to complain-- usually family members.

"Are those ALL dirty dishes?" "There's so much cat hair, have you cleaned recently?"

I have five cats. There will ALWAYS be cat hair SOMEWHERE.

I think they're referencing the game Fallout where bottlecaps are used as currency
