You may have seen those viral videos where a cat, peacefully eating, suddenly pounces upon discovering… a simple cucumber. The scene may raise a smile, and yet, behind this seemingly comical moment, lies a mechanism much deeper than a simple distaste for vegetables. So, myth or reality? Are cats really afraid of cucumbers? What if it’s not a vegetable issue at all…
What Really Scares Your Cat (Hint: It’s Not Green)

It’s not so much the cucumber that causes this instant panic, but rather the element of surprise . Imagine yourself enjoying your favorite meal, relaxed, in a familiar place… and suddenly, a strange object silently appears behind you. You’d jump too, wouldn’t you? That’s exactly how your cat feels.
Our felines have a highly developed spatial memory . They know exactly where their bowl, their favorite cushion, or your armchair ( now theirs ) are. When an unusual object suddenly appears in this environment that they know by heart, their ancestral instinct is activated. This is the famous startle reflex: a rapid reaction found in all animals to allow them to flee from potential danger.
Form matters… and it evokes an ancestral danger

Some experts put forward an interesting theory: the cucumber’s elongated, green silhouette, lying on the ground, could evoke that of a snake. Even if our domestic cats have never encountered a snake in their lives, they retain the reflexes of their wild ancestors. A thin, long, unknown, and silent object? All the warning signals light up in their little heads.
Which explains why other similar objects can provoke the same reaction: a cable, a banana, or even a soft toy. So it’s not a personal vendetta against vegetables from the squash family , but rather a mixture of surprise, suspicious appearance and survival instinct.
