nope, no negative effect. it doesn't matter if they ingest it, since it's just wheat. great odor control, and i clean mine once a day or sometimes every other day. it's just little pieces of wheat, my kitty has never had an issue with his feet. and i don't use liners and occasionally clumps do stick to the bottom, but i use my scoop like a spatula and they pop right off. it's flushable, but i usually have to break up the clumps a bit before they go down the toilet. all in all, i am a huge fan of this litter.shlanon said:So the Shweat litter has no negative effect on cats even though it is clumping? Since it is not made of clay? Just wondering. I switched from clumping to plain clay after being afraid that the clumping could be bad for my cats after possibly grooming and injesting it. But the non-clumping clay tends to start stinking MUCH sooner than I would like, even with the anti-bacterial version.
I think I may give Shweat a try. Is it hard pellets like Feline Pine though? I would prefer something a little softer on my kitties' feet.
