I don't have an automatice litter box, so I can't help with your first question.

I much prefer the scoopable litter. I have only used the clay rarely as it is more work for ME, ha ha. I have used Tidy Cats Scoopable for all of the 12 years I have owned cats, and they like it. The times I used the clay litter was on travels. I didn't like all the dust so yes, I think there is less dust with scoopable. I didn't like having to change the entire box, either. It could even be that she is rolling in used litter and that is giving her the itchies? Doesn't matter how often you are cleaning the box, no reflection on you. If she is rolling in in, she is going to pick things up, I suppose.



I hope you find something to help Chloe!
