It is possible to get cosmetic contact lenses that make your eyes appear to have slit pupils like a cat's. It is not possible to either change your eyes physically to have that pupil shape, or change them to be as sensitive in the dark as a cat's eye.
If you're a cat.
No. Nothing short of surgery or injury will change the shape of your eyes.
they are actually black but change blue because they are so young. My cat just had kittens and her kittens eyes are blue because her eyes are blue.
Probably not, but they might if they die with their eyes open but I'm not quite sure.

They change because when the cat is focusing on a specific object the pupil gets bigger to keep focus, when the pupil is a diamond shape that then means that the cat/kitten is not focusing on something particular
Like Big the cat's eyes ther're yellow
Well, because as we were younger our eyes were a grayish color, and as we age are eyes start to change colors. So, your cat is just transforming into it's natural eye color.(:
Hyperbole
I can't really explain in genetics, but I can in similarity. A colour of a Cat's fur can be like the colour of our eyes in a way. If one of your parents has brown eyes (with no trace of blue eyes) and the other had blue eyes, you would get brown eyes. So, the white Cat is the blue eyes and the black Cat is the brown eyes. Do you get that?
Not really, but there have been legends about evil witches who have the power to turn into cats when put in cat eyes instead of human eyes. You could imagine that, though. Or buy little marbles that look like cat eyes and I guess just hold em' up to your eyes! :) Witches don't do that. Just so you know. And you can't, but you could also like paint it around your eyes.
pandas see good because unlike most eyes their eyes are vertical like cat's eyes
