Erika- That's quite a story! I knew they loved to dig, but I have never given mine such an opportunity! To think they had dug such an impressive tunnel system is amazing!! Mine don't have that kind of freedom, so who knew? :) One thousand ferret kisses to your parents. I think their efforts to deter the digging is commendable. I know my parents wouldn't have been so cooperative! They would have gotten rid of the ferrets first - if they had allowed them at all! Debbie Riccio WNYFLFA Rochester, NY [Posted in FML issue 1294]
