Baby ferrets should not be disturbed or handled by humans for about the first week, because a Jill may feel threatened and might cannibalize her babies
Are the baby ferrets are old enough to be without their mother (weaned and eating solid foods), then there shouldn't be any problem putting them back with the mother.
For five ferrets, the largest cage you can afford as ferrets need room to move and exercise. Ferrets also need plenty of supervised time out of the cage for their health and welfare See related question and answer below for more information
Ferrets are not caged animals, but you cage them for their protection. Most ferret owners cage ferrets when they're not at home or unable to supervise them when free roaming. Ferrets need about 4 hours daily time out of their cage in a ferret proofed environment. Ferrets being burrowing animals by nature are subject to crawl and fall asleep into places that can be dangerous and you cannot get them out, like in major appliances, couches, recliners (very dangerous for ferrets). I personally do not cage my ferrets, but keep them in a bedroom totally ferret proofed so they are safe
You can keep them all in the same cage provided it has plenty of room and they aren't confined too much. A ferrets cage size at minimum should be at least 3 foot width X 2 foot depth X 2 foot height. A large, well designed cage for ferrets is a necessity especially if you plan on keeping more ferrets in the same cage.
Change your ferrets water at least once daily
ferrets are not cheap, caring properly for them is quite expensive. If you don't have the money for a ferrets cage and supplies, just get a dog instead.
Ferrets being very social animals should be allowed out of their cage for at least four hours daily. Ferrets are not caged animals, you cage them for their protection. Prolonged caging can lead to illness, stress related disease and aggressive or abnormal behaviors in ferrets.
You can put a ferret in a hamsters cage on a temporary basis as long as it's not being used to house hamster's as the ferret will kill them. A ferrets needs a large size cage made for ferrets.
if she keeps the baby out of her house it probably means she doesn't want it. so you have to keep the baby in its own small cage and keep it warm cos if it stays in the cage with its mother the mother will eat it.
No, ferrets cannot live in a plastic storage container, aquariums, etc. Ferrets need a large wire cage (cages made specifically for ferrets) with plenty of ventilation. Ferrets cannot be caged continuously and for their health, need several hours out of their cage daily.
Ferrets are nocturnal and they normally sleep 15-20 hours a day. Ferrets need daily activities outside their cage of about 4 hours
Ask the airline whether ferrets are allowed to travel, and if so, how must they travel (in a special cage?).
In most cases, yes they can - two of our male ferrets, Reuben and Ya'akob, have been happily sharing a cage for some time and other than the completely normal and short-lived squabbles that all ferret owners become used to, they get along perfectly well. Do remember that for the few hours each day when they're not asleep, ferrets are extremely active and as such require a large cage with plenty of space. if you're keeping two ferrets in one cage, it needs to be a very big cage. Unlike most animals, ferrets never fight over food which makes it far easier to house two together. Having said that, ferrets are highly intelligent creatures and as a result also highly individual, so if my ferrets - and indeed, all the other ferrets in the world - do something, it doesn't necessarily mean that your ferrets will do the same. Some ferrets actually prefer to be alone and some dislike all other ferrets, though the vast majority prefer ferrety company. Try putting them in the cage together and see what happens - there may be some fighting to begin with, but unless they're drawing blood let them settle. Chances are they'll be curled up together fast asleep before too long.
