Apparently, there's an underground network of ferrets in New York City. Which seems odd. Prairie dogs, I could understand.
The ferrets are illegals, and hide out in untold numbers in apartments all over the city, awaiting amnesty. The mayor has proposed lifting the citywide ban on ferrets, which delights ferret fanciers but has some residents worried about a mass weaseling. Ferret owners bristle at the notion that their pets are weasels, even though they are. Their fancy name is Mustela putorius, meaning stinky weasel. They're definitely not rodents. They have some things in common with rodents, just as we do, but they're way more tubular. In fact a good ferret can be stretched out to nearly five feet and only an inch in diameter, but only if you aren't going to use it for anything afterwards.
New York City prohibits the owning of a number of different kinds of animals, including rhinoceroses because of the stomping issue, and ferrets because of the biting--same reason dogs and cats are illegal in every state. But there's hope. A group of ferrets is called a "business." Perhaps with the new Republican wave, ferret fanciers can anticipate a nationwide deregulation.
