Having practically tested us throughout the supermarket range of cat litter, but with no one, regardless of whether cheap or expensive, were happy, we came across Green Cat. The first cat litter which I think does what it promises. It clumps incredibly good, so you what needs to be taken out of the litter box can take out without problems. It also binds the smell properly. Before that we had to evacuate at least every other day completely and refill the litter of our two cats. With Green Cat is sufficient, once completely empty the week and otherwise removing only the lump. Moreover, it also seems to taste quite well, our cat has tried the same times) In discounters a 12l bag costs 6. Here I paid for 72L 24. The individual grains are naturally lighter than in "normal" cat litter, so more lands outside.
The only drawback: The cat litter came in a big bulky box that postal workers had difficulty to drag the package at all to the front door. Please modify :)
