I think cirulating the air more will definitely help.

Our 3 litterboxes are in the basement. It's not a huge basement, but it's not small by any means either. With Tubby getting older, he sometimes doesn't squat as much as he should, and the very little of the urine actually gets in the litterbox. Most of it ends up being soaked up by the throw rugs I have under each litterbox. This doesn't happen too often, but after a few times there is a definite urine odor when you go to the basement. I wash the rugs every couple of months, but that only helps to a point because as you know, once the smell is in there, there's not much that can get it out.

So last year when I went to a cat show with Sara (Edwina's Secretary), there was this deodorizer thing. It's almost like a mesh bag and there's something like lava rocks in it. It's actually more of an odor "absorber." It says it will last forever, and if it seems to be losing odor absorbing power, to put it in the sun for an afternoon and it will rejuvenate itself. I was skeptical, but Sara said she had one in their basement for the mustiness and it worked real well. I went ahead and bought one (don't remember if it was $10.00 or $20.00) and hung it near one of the litter boxes (all three are scattered throughout the basement). I then went and washed the rugs and the litterboxes to get rid of the worst of the odor. And I have to say I'm am amazed at how well this thing works! Not once since I hung it up has there even been a hint of odor. Terry has a work table right near one of the boxes and he has complained about the odor before - even when everything is cleaned - and since I hung this thing up he hasn't complained once.

I don't remember the name of the thing, and I have no idea where to get them except at this cat show. If no one else knows what I'm talking about and where to get it, I will check it out tonight when I get home and give you a name and hopefully an email address. I would think that since you have a small apt., one of these should really do the trick, as long as you don't hang it in a closet or something.

I was actually thinking of getting one more for the basement, just to be sure. I was going to wait until the next cat show, but if someone knows where to get them, I'd order one right now. I've never seen them anywhere else, not even in the hundreds of catalogs I get.
