Vickie Ives Speir and her family of Karma Farms in Marshall, Texas (Woodlawn, Texas, actually, just north of Marshall) intentionally breeds cats with deformed front leg bones which render them incapable of getting around except through hopping in a motion reminiscent of someone using a pogo stick. She calls them the Twisty Cats.
Unfortunately, this is not illegal in Texas. Speir started publicizing the cats in 1998 and received a big backlash in return. She now pities herself publicly, considers herself persecuted, and vilifies, threatens and harasses the people who protest her actions and/or try to put a halt to it. Her husband has left her. The older of her two daughters, Victoria (Tori), has publicly supported her in this and her younger daughter, who is 16, has not said anything publicly against it.
