Which statement best describes dog and cat sight compared to human sight?

• A. Both can perceive motion and see well in low light
• B. They perceive details as clearly as humans
• C. They see more color than humans
• D. They cannot perceive motion

Answer: (A)

Dogs and cats are built for detecting motion and thriving in low light. Their retinas have more rod cells and a reflective layer called the tapetum lucidum, which together enhance sensitivity in dim conditions and help reveal movement even when lighting is poor. This makes them excellent at spotting moving objects and navigating in the dark. At the same time, their ability to resolve fine details isn’t as strong as human vision because they have fewer cone cells, which means sharper, detailed vision is not their strength. Color perception is also different; they don’t see a wide range of colors like humans do, primarily sensing blues and yellows rather than reds. So the best description is that they can perceive motion and see well in low light, while not seeing details as clearly and not seeing more color than humans.
