content: I have 3 rats. One female and 2 neutered males. I bought a litter pan for them and had been trying out different materials in it to get them to stop pooping everywhere. Nothing was working until I got this litter. I added it and tossed in a few of their little poops and within ten minutes they had used it. By the end of the first day they had all used it.They now use it for poop about 75% of the time, and for pee almost never.Pros:Works!Easy to clean, just shake and tilt the litter pan and all the pellets go to the edge and can be scooped out.Lasts a long time for the cost (2$ bag will end up lasting me 2 months).Does not make them sick from the dust.Cons:They do not like to pee in it.I will be buying this for as long as I have my rats. Excellent product.
