I've been trying to get my rats to use a litter box but after almost 2 weeks they dont seem to grasp the concept yet. I use recycled paper bedding throughout the bottom of the cage and have a litter box filled with aspen bedding that I made sure to put there previous droppings in. About three times a day I place all there droppings in the litter box but nearly two weeks later they seem to be showing little progress. I have read a thousand articles,posts etc,done everything instructed and it doesnt seem to be working. I've trained them to do other things in a matter of one or two days but they seem to be very stubborn on there right to poop wherever they want. Any advice? its getting a bit tedious. :?
