Hi All! I found a 'rice' box at the Ferret Store that I think is going to be just the answer! Its a smallish cardboard box full of edible peanuts that the ferrets can dig in, and if they eat any of the peanuts they turn to mush and biodegrade. The peanuts look very similar to white cheetos and feel like styrofoam, but they are warranted not to hurt your animal if ingested. My two guys really like fooling around in there and yes, I've seen evidence that Luke is eating or licking on them because a few have already got melt-y looking sides/ends where he's nibbled. (Just goes to show you just can't be too careful as I'd have never noticed that if it were plain rice or something!) Incidentally, if your order is over twenty bucks they ship free. Its an easy-to-navigate site and I recommend it. Kim Latas Spirit Lake IA [Posted in FML issue 3491]
