Yes, do it!!!! It is one of the nicest things you can do for your ferret. When they are used to wearing a harness from a young age, they don't even notice and will walk with you and enjoy all the outdoor sounds, sights and smells. I suggest using a very small retractable leash so that you can quickly regulate the distance they are from you. Make sure he is up to date on his vaccinations and remain very alert for other animals AND children approaching. You are also helping your ferret by acquainting him with the way back to his home...always try to give him free leash when he is getting closer to home and let him find the way. There are more tips than I could possibly tell you. But I will tell you that your ferret is a lucky little guy! You can check out my video (from a couple of years ago, wow that long?), showing us camping with our guys. Note they are always on harness and retractable leash (except when we are in the zipped tent). http://www.youtube.com/watch?v=Zofqn-MuFLk Lesley [Posted in FML 6813]
