Query: Leaks!

Should have read the reviews better before we pruchased. We have an older cat that has problems getting over the high sides of our existing litter box, so this was one of the 2 new ones we bought to try and combat that problem. The cats use it without issues, but imagine my surprise when I found the first big puddle of pee down the outside and on the floor. I figured one of them decided to mark the outside, so we cleaned, sprayed and started again.Quickly realized that the design & height of the sides and the not so tight edges which allow escape and leakage from our high pee'ing cats! So, today its going to the humane society and we are off to buy another high sided one with a hinged lid. Works so much better!Too bad can't return it since its not cheap!Jeez.
