^ any info about that animal?
I thought it was an owl first - I can see it's a cat but wondering how real it is (it *looks* real)

It's a Pallas' Cat.
I think they look very intriguing also.  Then again, I'm a cat person, so... yeah.

Lots of pictures here: http://www.arkinspac...hat-time-forgot.html
One cool thing is their eyes; the pupils are round instead of typical cat slits.  Beautiful creatures.


Me being a cat person as well, Edvard, your Pallas' Cat inspired me to learn more about cats eyes.

Or pupil shapes in general.  http://pets.thenest....cats-pupil-7069.html  Scalloped, square and W-shaped pupils?   :huh:

Round

Among the great cats, lions, tigers and cougars have round pupils. Round pupils give good vision in the daytime, and they can close to pinpoints to protect the sensitive inner structures of the eyes from too much light. They can also expand in low-light situations, such as dawn and dusk, to allow some night hunting.


Slit

Slit pupils can open and close faster than round ones, and wider, too. Your cat's eyeballs aren't much smaller than yours, but their pupils can open three times larger than yours. This lets her take advantage of the smallest amount of available light -- including starlight and snow glow -- for nighttime hunting. Jaguars and leopards haunt the dimness of the tropical rainforest but also come out occasionally on the open savannah to hunt at dawn and dusk. Because they spend most of their time in semi-darkness, slit pupils work best for them.


Horizontal

You won't find horizontal pupils on any cats, but lots of grazing animals -- goats, sheep, cattle, horses, kangaroos, hippopotamuses -- have them so they can see big cats (or other predators) sneaking up on them. They have three-dimensional vision for 330 degrees: almost all the way around their heads. That means that when you're riding a horse, he can see you sitting on his back.


Vertical

Cats that hunt primarily at night or in low-light conditions have vertical-slit pupils. Because they are predators and not prey, they don't need to see what's sneaking up behind them -- they're doing the sneaking. Vertical slits work well for domestic cats and many small wild cats. With vertical-slit pupils and horizontally opening eyelids, cats have exquisite and precise control of the amount of light that enters their eyes. They can even express feelings with the pupils of their eyes. If Fluffy's pupils are slits in daylight, she's calm and relaxed. On the other hand, if her pupils are dilated round in bright light, something's wrong -- she's probably ready to run for her life or kill something.
