There is something deranged about you.… The excessive concern you have for ferrets is something you should examine with a therapist.… There is something really, really very sad about you.… This excessive concern with little weasels is a sickness.… You should go consult a psychologist.… Your compulsion about—your excessive concern with it is a sign that there is something wrong in your personality.… You have a sickness, and I know it's hard for you to accept that.… You need help.
Ferrets are affectless, tiny-brained land-sharks that endlessly prowl their enclosures looking for something to kill. A neighbor's ferret nearly ate my pet iguana once when he brought it over. Luckily, Oogie took refuge up the top of a curtain and shat on the nasty little beast. The ferret also used to get loose, bring back the neighborhood cats, and stuff their dead bodies under my neighbor's fridge (I'm not a cat person either, but this still seems wrong).
Plus it gave off a weird, musky smell.
But a ban on them is a bit harsh. You wanna see a pet they outta ban?
The Nile Monitor (Varanus niloticus) is relatively common, and therefore relatively cheap to collect, so it turns up frequently in pet stores. It arrives as a cute lizard about the size of your hand, with bight yellow stripes down the side. Within a few years it has grown into a bad tempered, essentially untamable meat eater about three feet long. Then four feet long. Then five feet long, and you keep feeding it out of fear.
