Depend on where it's going to be kept - A cage is meant to be used indoors, as a hutch is for the outdoors. I would recommend the largest cage you can afford, as ferrets are not caged animals, you cage them for their protection.
use a hutch not a cage
A ferret should be allowed out of the cage for about 4 hours daily. Outside time of the cage, walks on a harness is fun!
Yes. Or board them at the vet or get them a sitter.You can use a pet carrier for temporary housing, I have two pet carriers (small and large) as I do not own a cage nor do I cage my ferret.
a cage a hutch
No they should be kept in a hutch or a cage.
He wants out. Is your ferret getting enough time out of it's cage?
What do you mean by mad? If your ferret is tearing up stuff it probably is not getting as much time out of its cage as it should, ferrets should have 2-4 hours out of their cage a day. If you are gone/busy all day, you could get a bigger cage (if you can afford it) and another ferret for a play mate; but you should still give your ferret(s) one on one play time with you.If your ferret is biting you then you can spray bitter apple on your hand and that will detour any biting; however, if your ferret is a kit it's probably just tryng to play with you. Remember that a ferret's skin is tougher than a human's, so a gentle nip to a ferret means come play with me! But to you it hurts, heres a link to how to nip train your ferret.
Depends on where you live, typically in the US the weather is not conducive for a ferret to live outdoors.
One may purchase a ferret cage at Petco, Petsmart, Atwoods, or Walmart.
That is the correct spelling of the noun "hutch" (a cabinet or rabbit cage).
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.
No the ferret cage does not need to be off the ground.
