8. Singapura
Source: http://www.petworlds.net
As the name suggests, the Singapura cat was first bred in Singapore. But another notable trait is that they are considered the smallest cat breed in the world, with each one varying in weight between a very light 4 to 8 pounds only. But while this very intelligent cat is also known to be quite clever, it’s also mischievous, knowing to attempt to climb anything and everything that they see fit.
