(A) Ferrets are Houdinis when it comes to escaping, but once loose they lack a homing instinct and seldom return to their hutch. A few years ago I had several
escapees running round the garden. To catch them I used simple live catch traps intended for mink and baited them with fresh rabbit or smelly fish cat food. I set them near the dark places where the ferrets could have been hiding and also near some chickens forwhich they may have been heading.
If you cannot catch your ferret, you could place signs in local spots frequented by dog-walkers and the general public. Contact all the local radio stations, vets, animal homes and the police. Ferrets, once spotted, are usually quickly reported. I do hope you regain possession of yours.
