Ferrets were used years ago on cargo ships for rodnet control. Watching what one of my ferrets did to a bird he got hold of makes me realize that he still has plenty of hunting instinct left. I think most ferrets do. Rmember the keyword here is instinct. I am suprised that you have a mouse with the ferrets in the household. Rodents are instinctively afraid of the scent of a ferret. Remember, these cute fuzzies were once considered ferocious hunters. As far as letting them catch the mouse, maybe one of our resident vets can give some input. As long as it is a mouse, not a rat, and the fuzzies are up to date on all shots, they should be OK. What I would suggest is letting them run around the house while you supervise. The presence of the ferrets should be enough to scare off the mouse. Beds: We don't have a problem with fuzzies in bed springs- we have a waterbed. Can't get under it, anlots of fun to play on top of it! Sympathy notes: To everyone who has lost a fuzzie over the past week, the Duck family would like to extend it's sincerest symapthies. -Mrs. Duck [Posted in FML issue 1333]
