Other litters that limit dust include those made from pine pellets or silica. Litter made from shredded recycled newspaper is also largely free of dust. Traditional clumping litters should be avoided if litter dust is a problem either for housekeeping or for a cat's asthma.
Other solutions to dealing with cat litter dust include using a covered litter box and setting the vacuum cleaner hose over the litter box as a new bag of litter is being poured in.
