does anyone know what type of litter is the best for eliminating smells? i've used normal non clumping clay litter for a while and after a few days of daily scooping, u can smell cat piss coming from it! i've tried recycled paper litter which is a bit better smell wise than non clumping clay litter but it still smells after a while...now i'm trying litter pearls, which are pretty expensive, but hopefully it will work! i also heard that clumping litter may not be so good for cats because they can get blockages from the dust of the litter that lands on thier fur which they lick it up when they groom themselves ! any ideas?
