Allerca, a company that is offering genetically modified cats at $4,000 each, makes you "agree" to a EULA before they sell you your puddy tat:
Purchaser shall not sell or transfer any Cat purchased hereunder to anyone other than an immediate family member, and shall not offer to any person the purchase of a Cat or any genetic material from a Cat, the rights Purchaser may have under this Agreement, or any other right related hereto, without the Company’s express written authorization.The cats are sold neutered.
Update: Patrick sez, "Allerca's headquarters was located in my apartment building, and they were evicted for non-payment of rent a few months ago. There was also an article in the San Diego Tribune, which questions their credibility."
Update 2: Waldo sez, "The president of Allerca agreed to create and sell my father a two-headed cat a couple of years ago."
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
