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?








565656565656
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 see 86 ! what does that mean ? Am I overcolored ? I am sure that cats can see colors. One of my cats couldn't see the red lazer spot because he was colorblind. The others did. Some of them like to play with a green mouse and the others prefer a white one !

Yep, cats can definitely see colours! I certainly prefer some coloured toys over others! And I love chasing the red dot!

That was great fun!
Only I see a 25 were you say there is a 15. What does that mean?

I think cats see just fine in color, maybe more enhanced as mine seem to steel all the rainbow of colors in my yarn basket! :)

Very interesting. I have also read that cats' eyes are more sensitive to motion than ours are (which makes sense of course). Interesting post! Happy Tuesday!

wow, that was cool. never knew that cats could see in color. Samantha probably wouldn't care, since she's Black and White, but Bebe is a Tortie, so she'd want to be sure that everyone could see!

I had never thought about the question of whether the cats see color or not. My cats haven't provided me with any evidence either way. But I will trust the scientists. :-) I do know that I'm not color blind, from your test there, as I saw everything I was supposed to see. ;-)

Whoops! Thanks Paula, I've corrected the 25 to 25. Gattina, I can't see an 86; you must have supersight.

Some cats could see colors, I have a book about cat could paint. Maybe next time I will find that to put on my blog.
