I don't blame him for vetoing it. Ferret's are vicious man-eating wild animals. It's sort of like making a pet of a bobcat, wolf, or raccoon.
Uh, no. Domesticated ferrets are very playful, friendly critters, once neutered...and they're legally REQUIRED to be neutered. I've handled a good many and never been bitten yet, which is better than I can say for cats, dogs, mice, or rats, all of which I've had as pets.
Now, I've had them try to steal my weddding ring off my finger, the decorative zipper off a shirt, the real zipper off a jacket, and the sunglasses off my face before...they're inveterate thieves. But, thus far, the worst injury gotten was a very much accidental graze from a claw allowed to grow too long.
