I hope the lid on your toilet is DOWN when Calvin uses it.....otherwise, he could easily fall in and would not be able to get out again. Remember the inside of a toilet bowl is smooth and slippery...some ferrets have been known to drown from falling in. Since bathrooms by nature seem to be particularly dangerous for ferrets what with rubber mats, toilets, pipes, etc., I close the bathroom door when the ferrets are out. You might want to consult the FAQ for some good tips on litter training. Debbie Riccio WNYFLFA Rochester, NY [Posted in FML issue 1203]
