I am with Wayne on this one...I think it is very unlikely it is spraying you smell. Chinadoll- I have had one or two people INSIST my house smells like cat. Frankly, because the overwhelming people that come over do not, I ignore them. It is possible that your mom/brother are imagining the smell?? When I go to houses with small children...I smell different smells than at my house..not good/bad, just different. So, maybe it is that.

I have six cats and six boxes. I do not clean mine with anywhere near the frequency that you do, and I don't have a problem. I do scoop once, sometimes twice a day. Now, sometimes, as Miss Meow says, the heat/humidity makes things smell. It isn't any different, in my opinion, then a human that, uh, you know!!! It smells!

Because of the incredible cold right now, most of my windows are closed. BUT, I still open things up once a week, and let some new air come in...sends the heat system in overload for an hour, but, I think you need to rid your house of old air.

Bottom line- if it doesn't bother you...well, it is YOUR place, right?
