Anyone have any suggestions on no dust cat litter? We have a kitty that is extraordinarily sensitive to dust, and her nose gets all congested whenever she has to use the box. Thoughts? Favorites? A google search brought me to pine pellets and Arm & Hammer clumping litter. Agree? Disagree? So far since I've been with this kitty, I've only used paper shavings or pine chips. She used to accept paper shavings, now it appears she isn't.
