Rats Love Being Tickled!

Who doesn't love a good tickle? It turns out that rats do as well! A 2016 study found that when you tickle rats, they emit tiny high-pitched rat giggles. This may come as a surprise to some people, especially those who think of rats as cold-blooded disease carriers. But it shouldn’t be too surprising when you consider the fact that animals have been known to show emotion and even have relationships with humans.
