There’s a viral video trend you might have seen lately: if you surprise your cat with a cucumber, she might respond by completely freaking out. She might hiss, shy away, or spring into the air. Silly cat, it’s just a vegetable! What a hilarious prank, right? According to National Geographic, not really. Jill Goldman, a certified animal behaviourist in southern California, advises against needlessly stressing your cat. Cats, she says, don’t normally see things like cucumbers on the floor, so you are “triggering the cats’ natural startle responses.” In general, be careful about shocking your cat with novel items. Your cat needs time to adjust to new objects and situations. Deliberately shocking her is unfair and potentially dangerous for your kitty.
