Is bentonite cat litter harmful to cats?

Expansive soil cat litter is not suitable for flat-faced cats and long-haired cats, nor for cats raised indoors, because there will be a layer of dust on the soles of the feet after the cats step on it, and the cat litter is easy to get stuck in the gap between the cat's toes and often step on the sofa and clothes at home. If a cat likes to sleep with its owner, the owner sometimes finds a few pieces of cat litter on the bed, not to mention how sour it is.
