Well I use carefresh ultra as well, and I understand what you mean about the smell (still 10x better than rabbit pee though! :vomit: )
But My rabbit doesn't even like bedding in his cage! He literally pushes every piece of bedding into the corner and never goes near it again! I actually use bedding just for his litterbox and it works pretty well. I am worried that he will get cold in winter though so I am probably going to get him a big bunny bed :biggrin2:
If you are talking about litter, my friend uses some sort of kitty litter that works REALLY well, it almost makes the litter box smell good :?:?:? but most beddings are good but beware of some with strong fragrances or some wood shavings can irritate the rabbits skin/affect the respiratory system.
Good luck :big wink:
