Funny you should bring this up. We were in San Diego this weekend visiting my hubby's sister and they use this stuff for Moses, their black and white cat.

There was no smell at all. I asked my borther-in-law about it and he said they really liked it. He said Moses only tracks it out of the box a little.

Hmmmm.....I wonder if I should try it in one of the boxes. I DID notice how loud it was when Moses was in there!

***Mozart and Bach....you guys are too cute!!!
