Tarrare (c. 1772 – 1798), sometimes spelled Tarare, was a French showman and soldier, noted for his unusual eating habits. Able to eat vast amounts of meat, he was constantly hungry; his parents could not provide for him, and he was turned out of the family home as a teenager. He travelled France in the company of a band of thieves and prostitutes, before becoming the warm-up act to a travelling charlatan; he would swallow corks, stones, live animals and a whole basketful of apples. He then took this act to Paris where he worked as a street performer.
At the start of the War of the First Coalition Tarrare joined the French Revolutionary Army. With military rations unable to satisfy his large appetite, he would eat any available food from gutters and refuse heaps but his condition still deteriorated through hunger. Suffering from exhaustion, he was hospitalised and became the subject of a series of medical experiments to test his eating capacity, in which, among other things, he ate a meal intended for 15 people in a single sitting, ate live cats, snakes, lizards and puppies, and swallowed an eel whole without chewing. Despite his unusual diet, he was of normal size and appearance, and showed no signs of mental illness other than what was described as an apathetic temperament.

Sounds like me, but I don't eat cats.
