I have been trying to litter train my boys. I think my attention hog of a rat Atticus is just being spiteful and standing on the edge of the litter box and going out the wrong side of it. I have been trying for a few weeks and seem not to be getting anywhere. they have two for the two older boys and the baby boys have one. They are still really little so I have been waiting a little for them to get bigger but Atticus and Gandalf just dont seem to be getting it. How can I train them to use it? I have never had such problems my old mischief picked it up in a few days and i didnt have any more problems but this time around its much harder.
