I don't know if anyone watches LA Ink. It's a show about a young woman that owns and runs a tattoo shop.
Anyway, she got a sphynx kitten about four years ago. He suddenly died a while back. I'm not sure exactly when, but the episode aired last week.
She said she came home and his back end was gnarled. I have no clue by what. I would think he was an indoor cat. Anyway, she LOVED Ludwig and was very torn up about losing him so soon and suddenly.

RIP Ludwig
