Yup. It was a hoax. Wiki explains all
Genpets are a mixed media installation art piece by artist Adam Brandejs. It is considered a hoax of exposure. The project has been shown in multiple galleries in Canada and Europe and has garnered some attention in the mass media.
Certainly got a reaction out of me. Then again I'm slow and it's late on a Friday afternoon. I'm not a big modern art aficionado, (possibly why I haven't heard about this before) but I must say I 'm impressed with this. While I was skeptical of it, I did ponder the implications of such technology. Which was the point.
