I used to have a guinea pig. Albino like that ferrat I believe. Can ferrats live easily in the wild?
Ferrets are domesticated animals, and can usually fix onto one type of food. It's very hard to even switch them to another type of kibble unless you slowly transition them over to it by mixing.
I tried to give my Eva a treat and she wouldn't even try it, until I dropped it into her food bowl and then she happened to eat some with her food. After that she'd eat the treat and would sit up for it. Before that she didn't even recognize it as food.
If a domestic ferret disappears and is not rescued it will likely starve to death quickly.
There are wild European polecats (a type of weasel) which are very closely related to the domestic ferret, but they're not the same as ferrets and are not domesticated. Sort of like wolves are to dogs. There's also an American animal called the black footed ferret which is a wild animal in the United States, but again, they're not the same as the domestic ferret.
