While I agree that the pellets were the best absorbent ones I so far used there are two disadvantages. The bag is quite small, I needed 1/2 of the bag to cover the areas my two rabbits use as their toilet outside the litter tray. They are using a litter tray I use woodshaving for but still wee in some other areas. The second issue I had was that the pellets totally disintegrated and I was left with a lot of strawlike dust. I felt it made cleaning the wooden hutch we have quite difficult.
