I'm posting the lost ferret tips that I've heard here. Two great tips to help them from being lost is opening windows that they have access to from the top instead of the bottom. And for doorways to the outdoors put up a plexiglass barrier (low enough to step over) between the regular door and screen door. post those flyers everywhere, ferrets can travel miles alert newspaper deliverers, mailmen, etc - people regularly in area, children too! search areas calling his name and squeaking a toy familiar to him put an extra cage or carrier outside with used bedding and litter in it, the scent may help him locate home contact vets, animal stores, animal control, etc go to animal shelters in person, may not be aware if a ferret is in check outside vents incase he is trying to reenter home on his own-and don't use in meantime check dryer tube, a/c - anything with access from outside Make sure he's not in the house. Make a list of ten places inside that he couldn't be - then check them. Make sure he's not stuck behind a bureau or in something. Even check places like the dishwasher and fridge. Don't empty trash or start laundry without being sure. [Posted in FML issue 4926]
