I'm all for not unduly distressing animals for human sport, but it's hard to see how the primary worry in this is how hard it is on the ferrets. Especially as ferrets are evil.
70-year-old Reg Mellor thought the world record of forty seconds was shamefully wimpy, and shortly after taking up the sport set a new record of over four hours.
"The ferrets must have a full mouth o' teeth," Reg Mellor said as he fiddled with his belt. "No filing of the teeth; no clipping. No dope for you or the ferrets. You must be sober, and the ferrets must be hungry-though any ferret'll eat yer eyes out even if he isn't hungry."An excerpt of Donald Katz's story about the king of the ferret-leggers is here. Reg is certainly a colorful guy.
A fragment of an unrelated second story about a voyeur follows, but can be ignored.
