Cats are not really scared of cucumbers. They are scared of a sneaky surprise.
What scares them?
A cat feels safest while it eats at its bowl. Then something strange appears right behind it without a sound. The cat jumps first and thinks later.
Is it a snake?
Some people say the cucumber looks like a snake, but experts doubt it, because some cats even hunt snakes. Almost any strange object would give the same fright.
Should you try it?
Vets say these scares stress cats out. They can even make a cat afraid of its own food bowl. So keep the cucumbers for your salad.
