The rarest pet cat breed in the world is the Turkish Angora.
Then besides the Turkish Angora the other rare pet cat breeds in the world are.
American Bobtail, European Burmese, Chartreux, Korat, Havana Brown, Burmilla and the LaPerm cat.
Those are the rarest pet cats in the world and can cost quite a bit of money to purchase.
Some of those cat breeds can cost $3,000.00 or more to purchase but they can be well worth the cost if you have the money to purchase those cats.
Or at least one of those cats.
