Example text

This wide range covers all the sounds important to cats, including the vocalizations greens probably appear as greys. In daylight, the pupils shrink to vertical slits to protect the eyes from glare. Cat vision is much less sharp than that of humans. Focusing such large eyes takes effort and cats are generally far-sighted, unable to see clearly within about 30cm (1ft) of their eyes. Their vision is much more attuned to detecting movement. Like many other predators, cats have forwardfacing eyes. Their total field of vision is about 200º, with an overlap between the eyes of 140º.

This overlap gives the cat binocular vision, allowing it to see in depth and to judge distances accurately, which are essential for success when hunting. NIGHT VISION In the dark, a cat’s pupil expands to an area three times larger than a human’s dilated pupil, allowing the tiniest glimmer of light to enter the eye. A cat’s night vision is further enhanced by a reflective layer behind the retina called the tapetum lucidum. Any light entering the eye that is not caught by the retina bounces off the tapetum and travels back through the retina, increasing the eye’s sensitivity by up to 40 per cent.

PARTICOLOUR BRITISH SHORTHAIR POINTED Coats in which the extremities are dark and the body paler are called pointed. In the Siamese and Persian Colourpoint, this pattern is controlled by a heatsensitive enzyme involved in producing hair pigment. The enzyme works only in the cooler extremities of the body, hence the darker fur. The pointed coat of the Turkish Van, with dark fur on the head and tail only, is a form of white spotting. ASIAN TORTIE PARTICOLOUR RAGDOLL SELF-POINTED SIAMESE BRITISH SHORTHAIR TORTIE TURKISH VAN WHITE SPOTTING Patches of white in a cat’s coat are produced by a dominant gene that suppresses the production of coloured fur.
