I do.....whenever someone comes over, I ask, "do you smell the kits?" No body has said they do, although in the heat of the summer, when you go down in the basement where their food and litter is, you can smell them....the humidity doesn't help. When we first got Trixie, and I was new at this kitty stuff, I tried buying the cheapest cat litter I could find.......well, I soon learned that the more expensive stuff really does keep the odors down/gone!
