Okee, the kittens are getting a bit older and I figured they would be using the litter sometime soon. I heard somewhere that you should not use "scoopable" or fine litter rather, that you should use the bigger chunked litter instead. Becaus they might try to eat it? Is this true? Does anyone have any suggestions on a special litter or should i use what Peepants and battly already use? I have been using Tidy Cats scoopable. Also I have been wanting to switch to one of the "earth friendly" natural litters anyway, has anyone tried any? Are they any good?
