... With three cats currently and decades of cat ownership, all litter know on the market when there is something new, this is usually tested out of curiosity, but these stray here is the best, which we because of our and the preferences of our cat / cats only use clumping litter (silicate, non clumping litter etc. have us and our Fellbömmels absolutely not convinced). Super Here: Very economical (we use anyway, only the fine clumping litter), beautiful natural color (more beige than asphalt gray), super grain (not rough, but not too finely, our cat love to dig in it), remains at twice sifting laaaaaange fresh daily, so that the toilet as a whole does not need to be cleaned often, but we will just delivered tilts and mixed only fresh straw (also use a huge loo - repurposed rectangular huge tub of Ikea without hood and with very high sides - because fit loosely times 3 bags of 10 l in), great value for money, and also very important: Without perfume / fragrances that have lost absolutely nothing in such a product.
