Hi nononicki, and welcome to pet talk! LOL LOL I was rollin' when I read your post. I know EXACTLY what you mean about the cat peeing over the edge of the litter box!! Is this a male cat thing?? Anyway, are there any covered litterboxes available there in Canada?? Covered litterboxes work great...not only do they keep all the contents inside but they also help in odor reduction. Good luck and let us know how it goes!!
