Ok I am going to be honest here.
I've had 3 ferrets. 2 at the same time (mother and daughter) and one a good few years later, a little boy who I rescued from a terrible breeder
.
They do make lovely pets if you handle them enough. They can give a nasty bite though if they aren't trained and handled alot. My little boy was very boisterous and wasn't handled and he did bite me quite alot and rather badly too. So they need to be handled regularly.
My first 2 lived outside in a hutch/house with a massive pen to run, climb and play in. The little boy I had, I let him live indoors in a really big cage (I hate that word). I would get him out during the day to explore and play.
They can smell too. People say getting them done will help this, but I'm not sure if that is true or not. Hobs tend to smell worse (males). But as long as you keep them clean and clean their living area frequent enough, I don't see that being too much of a problem.
If you get a female you must have her spayed, otherwise if not mated during season it could lead to illness and death.
Before I got my first ferret/s I did research. Look on Google, there is lots of info on ferrets, what they are like as a pet and how they need to be cared for etc.
