Cats have excellent night vision and can see at one sixth the light level required for human vision. [ 53 ] : 43 This is partly the result of cat eyes having a tapetum lucidum , which reflects any light that passes through the retina back into the eye, thereby increasing the eye's sensitivity to dim light.

Cat senses are adaptations that allow cats to be highly efficient predators. Cats are good at detecting movement in low light, have an acute sense of hearing and smell, and their sense of touch is enhanced by long whiskers that protrude from their heads and bodies. These senses evolved to allow cats to hunt effectively at dawn and dusk.
A specific type of NVD, the night vision goggle (NVG) is a night vision device with dual eyepieces. The device can utilize either one intensifier tube with the same image sent to both eyes, or a separate image intensifier tube for each eye. Night vision goggles combined with magnification lenses constitutes night vision binoculars.
1. A cat was a mayor for 20 years (yes, really!) For reasons we’re still unsure of, legend has it that a ginger cat called Stubbs ended up being a mayor for two decades in a small town in Alaska.
Their night vision is especially good due to the presence of a tapetum lucidum, which reflects light inside the eyeball, and gives felid eyes their distinctive shine. As a result, the eyes of felids are about six times more light-sensitive than those of humans, and many species are at least partially nocturnal .
Ragdolls are a fairly recent cat breed, having only been established in the 1960s by a breeder named Ann Baker in the US, and recognized as an official breed by the Cat Fanciers’ Association ...
The kiwi is a family of nocturnal birds endemic to New Zealand.. While it is difficult to say which came first, nocturnality or diurnality, a hypothesis in evolutionary biology, the nocturnal bottleneck theory, postulates that in the Mesozoic, many ancestors of modern-day mammals evolved nocturnal characteristics in order to avoid contact with the numerous diurnal predators.

The World Cat Federation has also adopted this classification, treating the Colourpoint Shorthair as a distinct breed. [13] Many Siamese cats from Thailand had a kink in their tails, but over the years, this trait has been considered a flaw. Breeders have largely eradicated it, but the kinked tail persists among street cats in Thailand.
