I use the grate thing and love it!! So nice they dont have to sit in their poop or urine.Is yours the corner litterbox? I was hoping to find one bigger as she grows but they dont sell the bigger boxes with the grate. She is only 9 weeks old now so she fits fine in it. I use the freshclean litter thats made of the recyled paper and I have no smell. What do you use for litter?
