Ferrets love new surroundings. If there is anything you can provide them with that will really make them happy and do their classic war dance of excitement, it would have to be new playgrounds for them to conquer. Since ferrets are quite adventurous, the only danger would be the fact that they may get too adventurous and get lost in the new surroundings.
So if you are taking your dear furry pal to the park or someplace that is new and exciting for them, make sure that you keep your eyes open to where they might be crawling next. Ferrets are quite fast creatures so you might even use this as an opportunity to jog with your pet.
The thing with the familiar surroundings which help ferrets is that they get to do their training better. You cant expect to train them well with good manners if you are not able to furnish some semblance of familiarity. The ferrets might not know it, but once domesticated, they will really need a place they can call home. They tend to relax in familiar surroundings, but then they can get bored so there is always a need to shake things up with a new toy or rearrangement of some of the things your ferrets play with.
Ferrets like enclosed spaces and are not as well-adjusted to noisy surroundings. In fact, this might alarm them or signal that they are being attacked. Some normal conversational noise may be tolerable, but anything in excess to that may be considered detrimental to your ferrets health.
Clutter is the ferrets best friend. They love taking things and treats new objects as toys, just as any innocent infant would in her crib. For the pet owner, this may be equivalent to Jumanji since the ferret can and will swallow anything in its midst. Its particular love for the unfamiliar may pose some danger to its digestive tract so make sure that you know the clutter they will be in before letting them loose.
Clean surroundings are good only for sleeping, which is daytime for ferrets since they are nocturnal creatures. Their sleeping area must be free from parasites so that they can have the sweetest dreams when they sleep. Over time, clean may translate to boring so you may find your ferrets bringing in new stuff to shake things up in his clean crib.
Indoors are fine for as long as your ferrets are in their resting stage. If the indoors is completely furnished with toys that will keep them amused, the ferrets will find no reason to roam. Though they are naturally wired to be wild and in the outdoors, ferrets may actually enjoy being the indoors if the place keeps them excited and motivated to explore.
Outdoors, ferrets are happiest. But you might risk losing them if the area is too wide and filled with trees.
How ferrets respond to their environment greatly depends on how they are designed. If you can give them various environments to play in, it will make them very happy. Like humans, always staying at home may make them dull and it will really pay to render them some constant dose of excitement.
