Russian Blue
Its most distinctive physical feature is the short, silvery-blue fur that densely covers its strong, sleek body. The silky fur tapers to a silvery color toward the tip. It is not patterned. Its head is V-shaped with a flat forehead and a long, slender neck. Its dark green eyes are round and it is known for changing its eye color twice. The dark blue-gray color of their eyes when they are first born changes to yellow at around 2 months of age, and then to green again around 5-6 months of age. However, most Russian Blues are crossed with British Shorthairs, so the green eyes are less common. The ears are large and pointed with a wide base. The tail is tapered towards the tip. They're very quiet and docile, but when their hunting instincts kick in, they'll bite anything they catch. They also have a low-pitched voice and rarely cry. They are affectionate and sensitive to their owner's emotions. They are affectionate with their owners and family members, but are wary of strangers and keep a low profile.
