Well, it would appear that the Genpets website is a hoax, so yours truly has been truly had! Thanks Connie for pointing this out. But am I glad. The concept deeply offended me.
A site called Snope GENPETS are actually artworks - made from latex and plastic - made by 24 year old Canadian commercial artist called Adam Brandejs. As per him Genpets was a way to have people sit and up and think about bioengineering and where the science might lead us.
The artist has similar works in the form of an animatronic Flesh Shoe (egad!) and and animatronic Heart.
