Cats eyes: Scientists have said that cats and dogs can see in ultraviolet ¿ so they can see things that humans can't - but experts are not sure why the animals need the capability
British researchers found that a whole plethora of mammals, including hedgehogs and ferrets can see in UV, giving them a better view at night among other benefits.
It was previously thought that only a handful of mammals could see ultraviolet light, but the new study could help scientists shed some light on why pets behave the way they do.
Ron Douglas, a biologist at City University London, in England told LiveScience: ‘Nobody ever thought these animals could see in ultraviolet, but in fact, they do.’
Light is made up of a spectrum of colours and humans can see from red to violet, whereas many animals, such as bees, fish, reptiles and amphibians can see ultraviolet wavelengths invisible to humans.
