Cats are good at many things (landing on their feet, sleeping, climbing things, hating humans), but one thing they're positively brilliant at is making us laugh.
Take a look at this list of funny pictures from Tumblr to see what we mean. Some of them are random, some are slightly worrying, and others are plain inexplicable. But if there's one thing they all have in common it's that they're guaranteed to make you smile. Don't forget to vote for your favorite!
