There are quite a few misconceptions on the true ferret. It is not a wild animal. The ancient Romans bred them, and used them like one would a cat, keeping their camps and homes free of mice and rats. In short, the ferret has been a domesticated animal for thousands of years. There are those who have a litter and dump it in the forest, thinking these animals will survive in what they mistakenly consider to be their habitat.
Nothing is less true.
Even though it resembles other animals in appearance, the ferret is and always will be depending on Man for its survival. If so, then you just picked a pet, which ll be unusual, as well as easy to keep. Ferrets can be kept in a cage, which is more common practice than letting them loose in the house. If kept in a cage, they are to be let out at least for two hours a day. Since they are daytime sleepers, they ll be snoozing the rest of the time.
