Some felines earned the name Hero Cat by scaring away an angry dog and saving the life of a little boy.
Others are scared of a lemon.
The following video was released in 2012, but then rediscovered recently by Tastefully Offensive. It features a very curious cat poking, prodding and swatting at a sliced lemon, clearly confounded by this piece of fruit.
The footage runs for over three-and-a-half minutes, but it's time-lapsed, which means the cat could have been doing battle with the lemon for hours and hours. Which is totally hilarious to imagine.
Watch them go at it here:
