Understanding Cat Vision

Cats are excellent hunters due to their eye adaptations for low light, but these adaptations come with drawbacks. Their large eyes and slit-shaped pupils allow them to see well at dawn and dusk, but they struggle with focusing on nearby objects. Cats have more rods than humans, enhancing night vision, but fewer cones, which limits their color vision and daytime clarity. Their eyes can't focus well on close objects, making treats appear blurry. Despite this, their strong sense of smell compensates for their visual limitations.

Why are cats considered masterful predators despite their poor close-up vision?

• They are very fast runners.

• They have a large brain.

• They can see well in low light conditions.

• They have a strong sense of smell.

What is the primary reason cats can see well at night?

• They have a special layer called the tapetum lucidum.

• Their eyes are smaller than human eyes.

• They have more cones than rods.

• Their pupils can dilate significantly.

How do the corneas and lenses of cat eyes contribute to their vision?

• They are proportionally larger, allowing more light to enter.

• They are less reflective than human corneas.

• They are smaller than those in human eyes.

• They are more flexible than human lenses.

What type of photoreceptor is more abundant in cats, aiding their night vision?

• Corneas

• Retinas

• Rods

• Cones

Why do cats have poor color vision?

• They have no tapetum lucidum.

• Their pupils do not dilate enough.

• Their eyes are too large.

• They have fewer cones compared to humans.

What happens to cat rods in bright light?

• They increase in number.

• They change color.

• They switch off completely.

• They become more sensitive.

Why do cats struggle to focus on objects close to them?

• Their eyes are too small.

• Their lenses are not flexible enough.

• Their lenses are too flexible.

• Their pupils are too narrow.

At what distance do cats start to have difficulty focusing on objects?

• 15 cm

• 10 cm

• 25 cm

• 50 cm

How do cats compensate for their poor close-up vision when finding treats?

• They use their hearing.

• They rely on their sense of smell.

• They use their whiskers.

• They use their tail.
