Bonsai Kitten
Bonsai Kitten was a satirical website which claimed that you could make a "shaped" cat by putting a kitten in a jar and letting it grow into the shape of the jar. It was named after bonsai, a Japanese art in which trees are shaped. The site was made by a university student with the nickname "Dr. Michael Wong Chang". The site claimed that many different shapes and "containment vessels" are possible, including a cube, a sphere, a wire cage, and even a Klein bottle. Supposedly, the kittens are force-fed through a tube, and the kitten's anus is sealed with super glue.
