The very name 'Twitter' indicates it is a service intended for birds, so it should come as no surprise that there are parrots twittering about their lives on the service.
But, when Twitter began asking the whole world 'What are you doing?', it perhaps didn't expect to hear answers from human organs, dead cats, whales and spacecraft.
We've rounded up eight of our favourite bizarre, non-human Twitter users, in order of how insightful they are, although all are astoundingly more interesting than Britney Spears.
8: I am Gordon's Liver
URL: @iamgordonsliver
Type: Human organ
Typical tweet: "Building my hopes up again for a healthy lunch, but expecting a liquid one."
This is the liver of a journalist called Gordon. Day to day, the personified organ comments on life inside the human body, providing a unique and easy-to-digest account of what it's like to work as an organ in a 21st-century male.
7: Pothos
URL: @pothos
Type: Unusually vocal plant
Typical tweet: "Thank you for watering me!"
This is a twittering plant. Obviously, it's quite a challenge to find a keyboard suitable for being typed on by leaves, so this plant's tweets are automated using moisture sensors wired up to a computer. When it gets too dry, it tweets its concern. Frankly, we'd prefer to see a Venus flytrap tweet about the weird crap it's eaten.
