Are cats afraid of cucumbers?

It’s a bit funny and heartbreaking to talk about it. It’s not that the cat is afraid of cucumbers, but the cat is a natural colour-blind, its sharp eyes can only distinguish between grey, blue and green. It is a biological instinct for cats to be startled by the sudden appearance of blue and green colours in their field of vision. This stressful situation can be physically and mentally damaging to the cat, and jokes should be moderate.
