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 ...
Other problems are house soiling, scratching furniture, and when a cat brings dead prey into the house. [45] There are 52 measured personality traits in cats, with one study saying "five reliable personality factors were found using principal axis factor analysis: neuroticism, extroversion, dominance, impulsiveness and agreeableness."

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 .
But even though most of them are, ahem, purr-day bad, we can't help but think they're hiss-terical. In fact, when it comes to coming up with dumb jokes that are all things feline-related, well ...

The largest letter on an eye chart often represents an acuity of 6/60 (20/200), the value that is considered "legally blind" in the US. Many individuals with high myopia cannot read the large E without glasses, but can read the 6/6 (20/20) line or 6/4.5 (20/15) line with glasses. By contrast, legally blind individuals have a visual acuity of 6/ ...
