A ferret is a domesticated form of a polecat, do you own ferrets?
No but I've held a ferret before.  do you have a ferret?
I don't but I know they typically have brown, black or white fur. What color was the one you held?
The ferret I held was brown and white.  It was so nice too and very curious.
That is so cool, ferrets typically live 7 to 10 years as well.
Really.  I had no clue they lived that long.  I'm wondering what they eat
I'm not sure exactly what they eat but I know that in some areas Ferrets are used for rabbit hunting. 
I had no clue they hunt rabbits.  I think they have to be trained for that function though.  I'm wondering how hard they can be to train?
Since they are domesticated they can't be that difficult. Ferrets have been outlawed in some parts of the world though due to how quickly they become Feral. For example hybrid, ferret polecats have been outlawed in New Zealand.
