When we got our first ferret he was 100% litter trained. When we got our second boy, they were 100% in cage and about 80% outside the cage. When we got our third girl, everyone was still 100% in cage and the boys were lowering they % outside the cage. By this time we made a bedroom/bathroom ferret proof. We now have 3 girls and 2 boys. Everyone is 100% in the cage and always have been. We have only had the one girl about 3 weeks. I'm proud to say ALL the girls are 100% INSIDE AND OUTSIDE!! Hurray for girls. Most of the time the boys go next to the litter box. Thank God they do this mainly in the kitchen so cleanup is easy. Once in awhile they do go in the frontroom. We have added a box where they go and even keep newspaper or plastic runner's near the box. Seems like boys like newspaper better. So most of the accidents have been right next to the litter box. Think what helped is for months I knew when they had to go and put them in the litter box right away. Not everyone has time for this. Will try harder at a better cleanup as one person mentioned.
