You won't be trying a different litter after using this. I love it!
After trying over 5 different litters, this is by far the best one for smelly mice (even for male mice!). I tried Chipsi Super, hanfstreu and pellets but nothing really worked. The cages were smelly in 2-3 days, and some types actually gave me asthma too. I also didn't want to go with pine shavings because it can be bad for their lungs. So I tried this one. Although expensive, it really eliminates the odour and absorbs moisture. It's not dusty at all, unlike hanfstreu, which goes all over the floor and clings to plastic. The mice are happy, and my own lungs are happy too.
Tip: don't try to skimp on this litter by mixing it with another. I tried that and the cage is not as smell-free as it was with purely Chipsi Ultra.
