I highly recommend this litter box. We have an older cat (14 yrs) and she’s been peeing and pooping outside her old box for a few weeks now (it’s quite unlike her). We tried everything: scooping every day (making sure the box was very clean); more litter & less; taking the box top off; and all sorts of different litter. Then we tried this box and it solved our problems! As soon as we put it down, she went right in! And now we have no more problems with her going on the floor! I think the low entry, larger space, and shallow sloping sides made a huge difference.
