I have a suggestion concerning your problem with the mouse (hopefully not mice). A few months ago I had a similar dilemma with a chipmunk. The poor little cutie had been evacuated from his home due to all the Midwestern floods in my area. He found the dryer vent opening and made his way down into my dryer. I noticed my ferrets were going nuts scratching at the boards in front of the dryer. Then one day I surprised the little nut eater and saw him making a beeline for the dryer. I went to the local hardware store and found a wire cage trap. It's long and rectangular with doors at each end. You set it up with the doors open and something tempting like cheese or in my case sunflower seeds on the tray in the middle. The little mouse will enter the cage and press on the tray to get food and the doors trip shut. I had captured my little invader in less than ten minutes and set him free unharmed. I promptly secured my dryer vent so he couldn't visit my ferrets and myself without being invited. He now has a hole that runs under my concrete patio and I treat him with sunflower seeds everyday placed down his humble abode. So if you don't want to have to harm your little visitor look into getting one of these traps. I know mice have a nasty habit of chewing on electrical wires and a tasty mouse would look awful good to some ferrets since ferrets were once(and still are?) trained to be used in netting rabbits. Speaking on the subject of culinary delights you also asked if ferrets eat bugs. MMMMMMM, you betcha! During our lovely flash flood season I had alot of waterbugs in my basement. I would occasionally find a wing here and a leg there and thought "what is going on?" One day a fat waterbug crawled in front of Weezul. He pounced on it and proceeded to munch away. I have also found Teebone licking his lips after supping on one. Personally I will stick with my rice cakes. I don't see any harm with the bug eating as long as they haven't been recently sprayed with bug killer. Bon Apetit! Judy and the little bug lovers, Teebone and Weezul [Posted in FML issue 0666]
