I have a LARGE JUMBO litter box to try to keep the litter in the box and not on floor. I am EXTREMELY allergic to the clumping, clay type litter, the clay litter, and dust from most litters EVEN if they say they are 99% dust free that is very far from true. Now i have tried the pine pellet litter and it is the MOST dust free i have found.... but it doesn't clump, sits at bottom I am constantly digging the wet part (the litter disintegrates and stays at bottom wet) out of the box and replacing with clean litter. it is very messy but not dusty and still gets litter on the floor but not as much. I have tried the corn, cedar pine litter and it is very dusty even tho it clams not.... the corn dust covers the inside of box.... the smell of the cedar and pine is deliteful but the litter is very lite and the firsrt time i put it in box i put it in a box with shorter sides, and she thought it was fun to hit the litter and watch it fly in the air over the sides. I put it in the jumbo box and she doesn't do that any more but the litter is still flying over the sides onto the bathroom floor. The Bathroom is so small that it is infront of toilet and u feel like u could put your feet in it when U DO YOUR business. i have one other rroom i could put it in but don't know how to keep the litter from flying over the side and of course the dust is terrible. SOOOOOOOOO .... the best thing about the litter is it clumps, sort of, and it smells wonderful..... no peeee odor. So....SUGGESTIONS.....BOX? LITTER? PLACEMENT? DUST? HELLLLLLLLP!!!!!
