The Russian Blue is known for its blue-grey fur and alert expression.

The greatest differences between a Korat and a Russian Blue cat include their head shape, fur type, and place of origin. The Korat has a heart-shaped head, originated in Thailand, and has a single coat of short, fine fur that is light blue at the root and darker as it grows before ending in a silvery tip. The Russian blue cat has a wedge-shaped head, originated in Russia, and has a double coat of fur with silvery guard hairs.

These are some of the most pronounced and easily identifiable features of these cat breeds. They are hardly the only way to tell them apart, though. Let’s go in greater depth about these creatures and learn how to tell them apart with greater ease.

A simple way to tell these cats apart is by their head shape. The Korat has a heart-shaped head, giving it a plush, loving look unless it’s annoyed. The Russian Blue cat has a wedge-shaped head, so it has a more severe look to it.

Korat vs Russian Blue Cat: Ears

These cats also have differently shaped ears, and that can help to distinguish them. For example, the Korat has ears with a wide base and a rounded top. Generally speaking, the Russian Blue cat has longer ears that are pointier at the end. Although this may not be an obvious way to tell a difference between the two creatures, it’s helpful.

Korat vs Russian Blue Cat: Eye Color

Both these cats have noticeable eyes when they are purebred. The Russian Blue Cat is known for its beautiful and intense emerald, green eyes. The Korat can also have green eyes, but they can be darker green with a light green fringe, too. The Korat is well-known for being one of the cats with the meanest faces, and their eyes contribute to that look.

Korat vs Russian Blue Cat: Body Morphology

The Korat has a semi-cobby body, so it’s a somewhat compact cat with a thick body and long legs. The Russian Blue cat has been called “semi-foreign.” That means the cat is somewhere between the long breeds like the Siamese, a popular breeding choice for this cat, and a compact cat.  

Korat vs Russian Blue Cat: Place of Origin

As the name suggests, the Russian Blue cat comes from Russia. The Korat comes from Thailand. In that nation, the Korat is known as a cat that brings good luck, and it is often given as a gift rather than sold.  

Korat vs Russian Blue Cat: Fur Type

The fur of the Korat and Russian Blue is the biggest point of divergence between the cats. The Korat has a single coat of fur, but the Russian Blue cat has a double coat of fur. Aside from that major difference, the cats still have major differences in their fur.

For example, the Russian Blue cat has short and thick fur. Their blue-gray-black fur results in overall bluish color. Moreover, the guard hairs on one layer end in silvery tips, so this cat can look like it’s shimmering in the right light.

The Korat has a single coat of fur that is described as short and fine. The fur is light at the root, darkens throughout the length of the hair, and then ends in a silver tip.

Although both cats have gray hair overall, the differences between them are apparent when you look closely or touch the cats.
