OK, now I'm getting fed up. I've been using the cheap clumping cat litter for the past 8 years....now I'm getting sick of the dust and just now I bent down to kiss Max and he smells like fresh cat litter out of the bag. There is no real stinky smell around here except for the fresh cat litter.

I have done a search because I know there are threads here about the same subject but none of them answer my one question. Should the new litter be added gradually or can I just dump the old and bring in the new?

I'm still not sure what I'm switching to, but a friend of mine (who I cat sit for) uses Yesteday's News and it's awesome. You don't scoop the pee, just the poop and it's flushable. A complete change is done once every two weeks (she has two cats as well). Not once, have I noticed any smell in her place.

Anyway, any advice would be greatly appreciated. Thanks.
