My cats and I are very pleased with the Thomas stray. Personally, I find it better than the clumping litter lot. But opinions are very divided yes .. I've tried different litter (normal + clumping litter) + must say that I am the best Thomas stray get along .. While it is not completely dust free (I always order the 30L bag and the rest is already sometimes quite dusty, but I think that's in pretty much any stray so), but my cats take it at best. Some litter smells very unpleasant even when it comes out of the box. The Thomas scattering is very neutral. I always ordered the 30L bags and this versandfrei sent for 9,95Euro get (prime) .. Unfortunately, there is so not a cheap deal at the moment. But once there, the stray again as low, I will first strike right =)
