Dali and Babou
Salvador Dali had a pet ocelot from Columbia called Babou. He used to take Babou everywhere. He took Babou with him when he sailed across the Atlantic Ocean, had him stay with him at hotels and even took him to restaurants. Crazy stuff considering ocelots, also known as dwarf leopards, are fiercly territorial and will fight to the death to protect their turf.
