Squirrels are rodents. They hate and fear cats, and with good reason, because cats can climb trees. If you have squirrels on your property, you are probably aware that when they see a cat, they immediately head to the highest part of the nearest tree and raise quite a ruckus, chattering noisily to one another. This distinctive chatter (which some people mistake for birds) is both a cry of fear and a warning to any squirrels in the vicinity that—horrors!—a cat is nearby.
