Well not so much trouble but it is a pain in the bum for me! (No pun intended)
Whenever my two boys go to use the facilities they end up taking half of the litter with them when they go to walk away. I keep finding it all over the house, unless I hover 4 times a day - sadly I'm not that much of a domestic goddess. Am I using too much litter, or is it just one of those things? Does anyone else have this problem?
Also I've noticed that Vader gets a little confused when he is attempting to cover his *business*. He seems to like to dig everywhere, except in the tray (ie the floor and the wall). It's not an issue, but he makes a right racket!
