I am a rat person who has recently tried this product for the first time and give it two thumbs up! It seems to be holding odor down much better than chip type bedding and other commercial litters I've used. In fact, I have been able to wait longer between cage cleaning times, which is a big plus when you have 6 cages! It is also easier to pick up if any lands outside the cage on the carpet, unlike the thorny bits from chip bedding that embed themselves in everything (a pain to try to vacuum up or wash out!).
The rats seem to like it, too. They dive through it like kids playing with confetti. I will happily use this product again.
