Can cats see in the dark?
Cats actually do have much, much better night vision than people do. It's been estimated as about 10 times better than how people see at night (or the difference between how you see stuff on a night with a full moon vs. a night without moonlight). They can't see if it's totally dark though, it's just that they're better with less light. Cats have an extra layer of tissue in their eyes that reflects even more light back into the retina, letting them see even with very little light available. That's also the reason why cat's eyes glow in the dark - what you're seeing is a reflection of light from this membrane.
