It's been about two weeks since I wrote about the sores on the sides of my white boy, Silverado. I removed the verticle tunnel inside the cage. He had to go down and up it for potty and general getting around. I am pleased to report that he is almost all healed now, fur is regrowing and he looks much better. I would encourage anyone who uses the hard tunnels to examine their ferrets for signs of problems on the sides and backs. If so, do something. Remove them, save for excercize outside the cage, use for a planter. But look for an alternative play system. If size of the ferret is a problem try to find something larger, such as concrete forms. Not as much fun but safer. Carol Owens, Ferret Friends, Tucson AZ [Posted in FML 5462]
