It is a safe to use with all small animals, rabbits, birds, reptiles, ferrets and cats. Eight quart package lasts 30 days for three small animals! RattyRat's Review: Works as a litter only. This is one of the best litters you can get. It is extremely odor absorbent, dust free, fairly comfortable for your rats to walk on, and lasts longer than any other litter out there. This is a very safe litter for all your rats. The only downside is that it is very expensive and hard to find.
