Munchkins are awesome! I'm about 99% set on getting one or two myself. I've seen them priced between $250 and $600, but I suppose that's going to vary based on quality and breeder. There are some munchkins that do not have the short legs gene so they have normal length legs, but are still great kitties. They are found in all colors, and both longhair and shorthair.
There are some super pictures of munchkins SandKats.com
, which is the cattery of our very own Sandie and Ken! I'm sure they will be able to answer any other questions you have.
