Good for the first week..
My tomcat tried to taste it a few times but eventually stopped. I thought, "aha, he'll love using it for his needs"... absolutely not T-T, he wouldn't set a paw in it and avoided it as much as possible. My female cat went on it straight away, and it clumped well.
There was less dust than the Tigerino Sensitive according to my air purifier. Unfortunately, the filling started to smell weird after a while. The scent was quite strong so I had to throw it away.
