do all british shorthair cats have yellow eyes
British Shorthair The British Shorthair is a relatively powerful-looking large cat, having a broad chest, strong thick-set legs with rounded paws and a medium-length, blunt-tipped tail. The head is relatively large and rounded, with a short muzzle, broad cheeks (most noticeable in mature males, who tend to develop prominent jowls) and large round eyes that are deep coppery orange in the British Blue and otherwise vary in colour depending on the coat. Their large ears are broad and widely set.[5]
Monocular deprivation David Hubel and Torsten Wiesel (who won the Nobel prize in Physiology for their elucidation of receptive field properties of cells in primary visual cortex) first performed the technique in felines.[1] Cats (or kittens), although less-closely related evolutionarily to humans even than rodents, have a remarkably similar visual system to humans. They found that ocular dominance columns (the orderly clustering of V1 neurons representing visual input from one or both eyes) were dramatically disrupted when one eye was sewn shut for 2 months. In the normal feline, about 85% of cells are responsive to input to both eyes; in the monocularly-deprived animals, no cells receive input from both eyes.[2]
