Can cheetahs see at night like other cats can?
I know that cheetahs would avoid nocturnal behavior because of lions,hyenas, and leopards but lets say a cheetah walks into a dark room thats not pitch black would it be able to see as well as the average cat?

yes, its a matter of rods in the eye. As with other predatory cats, cheetahs have a lot of rods. Probably not as many as a nocturnal feline, but plenty to see by reduced light.
yeh they have lots of rods, that other guy who just said that was right, but that isn’t the whole reason, they have a reflective membrane behind the eye that reflects light back forward, so it hits the cone cells twice. thats why cats eyes are reflecty.
there’s a special word for it but it escapes me..if you wiki cat eyes it’ll be able to tell you i expect
all cats have it, i’m fairly sure
hope i helped
I believe the reflective layer is called the tapedum lucidum, though I probably didn’t spell that just right but it’s close…either way, ANY animal that has this reflective layer can see reasonably well at night, including cheetahs. Many mammals and some fish like sharks have this reflective layer, including herbivores like cows and deer (which is a good thing, not only for the deer, as a pair of glowing eyes in the middle of the road at night at least gives you a chance to hit the brakes…).
But back to the cheetah – while it has an eye structure much like any other cat (and like all “big” cats it has round pupils instead of slits like little cats), it does have an adaption to being diurnal (active primarily in daylight) – the iris of its eyes are darker in color than most other cats like leopards and lions. Animals that are day-active (and especially those that live in open areas where they get full sunlight exposure) tend to have darker colored eyes than those that are nocturnal or crepuscular (dusk and dawn active). This darker pigment helps protect the eye against sun damage, and an example can be found in humans: people with light colored eyes (pale green, blue, light grey, etc) have a higher incidence of cataracts (all else accounted for) than people with dark eyes (brown, dark green, hazel, etc).
So this is the main difference between a cheetah’s eyes and those of a lion or leopard.
