Ferrets, banned as pets in California for 70 years, may soon be back in favor. Some hope Arnold Schwarzenegger, who worked with a ferret in Kindergarten Cop, may legalize the animals. “We have an inequity here and this man is sensitive to that kind of thing,” said Jeanne Carley, founder of Californians for Ferret Legalization. “The state wildlife agency doesn’t regulate cats and dogs, so why should it regulate ferrets?” The ban was put in place because of fears ferrets might weasel their way into the wild and ravage populations of ground-dwelling birds.
