British researchers explain why pet owners might suspect that their animals have a sixth sense and why they seem to be ‘spooked’ by nothing at all. The strange behavior of cats and dogs can be explained because they have ultraviolet vision – so they can see things that humans can’t.
According to dailymail.co.uk: The lens of the human eye blocks ultraviolet light, but in some animals UV can reach the retina and the light is converted into nerve signals, which travel to the brain and are processed.
