Carrie wrote in asking how to attach a hi backed litter pan to the cage. What we did is you either take an electric drill (or a nail heated over a lighter works to, use pliers to hold) and drill or poke two small holes in the litter pan, up towards the top on each side for a total of 4 holes (2 pairs of 2). Then you take some wire (twist ties will even work, but are not very durable) and loop them through each pair of holes and twist them onto the cage. Now this makes it hard to change the litter, as we discovered a week after doing it, so we changed our plan. We took a small sized cat litter box that the hi backed litter pan would fit into and wired this into the cage as I just described. The hi backed litter pan then fits into the cat litter box. The fact that the cat box is wired down prevents it from getting dumped over and the ferret litter box is easily removed (by HUMANS) for cleaning. Hope this helps, Leigh [Posted in FML issue 3158]
