#6 American Curl – $2,200

In 1981, Grace and Joe Ruga took a stray cat with silky black hair and funny curled ears into their California home. Every single American Curl in the world is a descendant of Shulamith, the stray cat that made the Rugas a fortune. Their pixie-like features are thought to be the results of a Lynx cross, though some believe it to be a mutation.

#5 British Shorthair – $3,000-3,500

The British Shorthair wasn’t always an expensive breed. Before World War II, their population was numbered in the tens of millions. However, so many died during the Nazi occupation of Europe that they were considered extinct in the 1950’s. In 1967, the American Cat Association surprised everyone by confirming one breeder’s claim of having a pure British Shorthair.
