cats_are_scared_of_cucumbers_(meme)
Cats or cat-related characters acting scared, shocked, nervous, cautious, etc. towards the sudden presence of a cucumber. Often resulting jumping, puffing up, wide-eyed, screaming, backing off, etc. In reality, they are actually spooked by something appearing behind them when it was previously not there, so other objects other than cucumbers can also spook them if done the same way.
