I think I know what the problem was. As you know I have 2 girls and the one was having accidents alot. I think both of them using the litter box (even though the biggest one) was still too small. I now have a tray (approx 2x4 feet) I put a long pee pad to cover the entire thing and I havent had an accidnet since

I know that seems big to have around but its not as big as you think. Having two girls leaves me no choice but to do this. They are tramping right up on the tray with no problems at all. I"M SO HAPPY!!
