A cat's visual acuity is anywhere from 20/100 to 20/200, which means a cat has to be at 6 metres to see what an average human can see at 20 or 30 metres. Cats seem to be nearsighted, which means they cannot see far objects as well. The ability to see close objects would be well-suited for hunting and capturing prey. [2]
A reference value above which visual acuity is considered normal is called 6/6 vision, the USC equivalent of which is 20/20 vision: At 6 metres or 20 feet, a human eye with that performance is able to separate contours that are approximately 1.75 mm apart. [9] Vision of 6/12 corresponds to lower performance, while vision of 6/3 to better ...
Domestic cats' behavioral and personality traits cannot be predicted from their coat color. Rather, these traits depend on a complex interplay between genetic and environmental factors. [31] Not all cats are attracted and intoxicated by catnip, which only affects about two thirds of them.

X represents the Greek letter chi , the first letter of Χριστός ( Christós ), "Christ" in Greek, as found in the chi-rho symbol (ΧΡ) since the ...
In the term "20/20 vision" the numerator refers to the distance in feet from which a person can reliably distinguish a pair of objects. The denominator is the distance from which an 'average' person would be able to distinguish —the distance at which their separation angle is 1 arc minute .
Cats are "obligate carnivores," meaning in order to stay healthy a cat's diet is primarily protein, according to the American Society for the Prevention of Cruelty to Animals. Eggs are a great ...
Skin disorders are among the most common health problems in cats and have many causes. The condition of a cat's skin and coat can be an important indicator of its general health. Cheyletiellosis is a mild dermatitis caused by mites of the genus Cheyletiella. It is also known as walking dandruff due to skin scales being carried by the mites ...
