Cats are scared of cucumbers mainly because the sudden appearance of the cucumber behind them surprises them, and its shape and color can resemble snakes or other predators, triggering a natural fear response. This fear is amplified by cats' natural caution as both hunters and prey, where unexpected objects can cause alarm. However, some experts believe it is more about the surprise and the unfamiliarity of the object appearing suddenly, rather than an inherent fear of cucumbers or snakes specifically. Additionally, scaring cats with cucumbers can cause stress and anxiety, so it is generally discouraged to prank cats this way.

Reasons for Fear of Cucumbers:

• The cucumber's green color and shape resemble snakes or predators that cats instinctively fear.
• Cats are very sensitive to their surroundings and dislike unexpected surprises, especially objects that appear suddenly behind them.
• Cats have vision adapted to detect movement rather than still objects, so a sudden still object appearing unseen startles them.
• Some experts note cats do not have a natural fear of snakes per se, as some cats hunt snakes, but the suddenness and novelty of the object is what causes the jump scare.

Effects on Cats:

• Scaring cats can lead to anxiety, stress, and long-term behavioral issues.
• It can lead to mistrust of their owners if the cat associates the owner with the scare.

Thus, the common interpretation is that cats' fear of cucumbers is a mix of their natural caution around snake-like shapes and the surprise factor of an unexpected object appearing suddenly behind them, which triggers a fight-or- flight reaction.
