I don't think it's real, but the face someone stuck teir cat in a glass thing, even just for pictures?!
Directly from Snopes.com:
The "Bonsai Kitten" site displays no actual pictures of the finished product. There are plenty of pictures of kittens in jars which can comfortably accommodate them (cats are quite elastic and can fit into very small spaces without discomfort), but there are no photographs of molded kittens on display.
