Cats On Tuesday: Can Cats See Colour?

While people used to believe that all animals are colour-blind, modern studies show this is untrue.

Cats’ retinae have an arrangement of rods and cones just as ours do.

However, scientists point out that the number of these suggests cats are pretty good about colour in general but not quite as good as we are at distinguishing subtleties.

I wonder what numbers Scoop and Au would see in these Ishihara dots?

If your colour vision is perfect you should see 56, 45, 29, 25, 8, and 6.

If you see a lot of dots instead, take a look at Ishiwara Test for Colour Blindness and check out Wikipedia's article on Colour Blindness too.

I have heard this more recently. It used to be believed that cats see basically black and white and red.

I bet they'd see tunas in those dots. Lots of tunas.

Seems cats can make out blue and green.

That was way cool in any color!

Angel Simba said...

I can see the colored numbers. I hope Simba would be able to also.

Inigo and D'Artagnan are looking for tunas EVERYWHERE!

We always wondered if cats could see colours as they usually have gone to more brightly coloured toys.

We have always thought that cats could see some colors just based on behavior. Tasha has a bright yellow blanket that she can spot from across the room. (It could be something else, of course, but she really seems to be able to see the color.)

I have always thought cats could see color, even though they said they couldn't, because we have always had cats that prefered toys of certain colors.

Oh, check your email, we resent your NKC blog contributor invite so it shoudl be there!

I know cats can see colour because my Rowdies always know which bowl is theirs. Also, Chloe used to eat Froot Loops (who says cats can't taste sugar?) and when we pour some into a plate for her, she always picks out the red ones and eats them first, so we know she can see red, at least.
