"Okey....blah blah blah.....seriously this is a wonderful box. Last year we adopted two older female cats, one torte calico, the other a black point siamese...both around 12 years of age. One definitly an indoor out door (NOW A TOTAL INDOOR)....I have several dogs, who LOVE 'kitty gormets'.....If the box is placed under a desk or table, the dogs can't get in...if out in the open, we see doggie hind feet sticking out of the top....so if you have a medium to large dog, they can still get in if left out in the open. Love the liners, and yes my girls have all their claws....yes they do punch holes in the sides of the liner, but never the bottom, and the liner has not yet ripped when cleaning out. I scoup one week, and do a total dump the next. I have two of these boxes, and would never use anything else."
