Are Cats Colour Blind? What Your Cat Actually Sees

In this guide

It is a myth that cats see only in black and white. Cats do see colour, just a narrower and less vivid range than we do, and understanding this can genuinely change how you choose toys and set up their environment.

What cats can and cannot see

Human eyes have three types of colour sensing cone cells, tuned to red, green and blue, which is what allows us to see such a wide spectrum. Cats have far fewer cone cells overall, and most research suggests they see mainly blues and yellow greens well, while reds and pinks likely appear as muted greys or greenish tones. In practical terms, feline colour vision is often compared to red green colour blindness in people.

Where cats outperform us

What cats give up in colour range, they more than make up for elsewhere. Their eyes are built for hunting in low light, needing roughly six times less light than human eyes to see clearly, and they are far better than us at detecting even the slightest movement. This is why a cat can spot a moving insect across a dark room but seem to completely ignore a brightly coloured toy sitting still on the floor.

What this means for toys and enrichment

• Movement matters far more to a cat than colour, so a plain toy dragged across the floor will usually get more interest than a bright toy sitting still
• Toys in blue or yellow tones may stand out more clearly to your cat than red or orange ones
• That red laser dot your cat chases so enthusiastically is seen mainly as a moving point rather than a red colour
• When picking new toys, blue or yellow options are a reasonable first choice if you want something that stands out visually to your cat rather than just to you

When vision changes are a concern

While colour perception itself is not something to worry about, a genuine decline in your cat's overall vision is. Bumping into furniture, hesitating on stairs, dilated pupils, or a cloudy appearance to the eyes can point to conditions such as retinal disease, high blood pressure affecting the eyes, or cataracts, and are worth a prompt vet visit rather than being put down to ageing alone.
