Fresh Step Multi-Cat Formula Review

We have tried several different brands of cat litter looking for one that won't track all over our floor.  Our cat box has very high sides, but the cats still manage to track it all over the floor of the utility room and even out into our kitchen!  Yuck!!!  My husband is a neat freak and with our new little one now mobile, this drives me nuts!   I am constantly vaccuuming it up.  We were hoping that Fresh Step would be different, but it is still ending up all over my floor.  It does seem to contain the odor so our laundry room doesn't smell when the cat box has been used, but the tracking of the litter drives me crazy!  I would love any input if someone has found a litter that doesn't end up on the floor.   We have tried Tidy Cats, Yesterday's News, and several other brands with no success.  We do have two cats, but the litter we purchase always specifies multiple cats, so I don't believe that's the problem with the litter ending up on the floor.
