Unfortunately Not Odourless
My cats like to use it for peeing, but they refuse to do their big business in the litter – they'd rather go in front of the litter box. Unfortunately, I'm extremely sensitive to smells and I notice a slight ammonia odour within a 3-metre radius of the litter box after just 3-4 days, although my guests haven't noticed anything like that. It doesn't create any dust at all, which I thought was great.
