I saw some guy walking a pet Emu down the street on youtube. People do keep a lot of strange animals.
I have seven here, but I don't walk them down the street! Women in Paris and Milan in the forties and fifties often walked pet cheetahs and the "artist" Salvador Dali often walked his pet anteater "Avida Dollars", an anagram for Salvador Dali, in Paris.

At other times he was pulled by a pet goat in a wicker cart.
Phyllis Gordon, the American actress was regularly seen at pavement cafes in Paris with her pet cheetah

When I lived outside Stockport the woman who owned a boutique called Seven Miles Out on Wellington Road, the main A6, had a black panther on a gold chain in the shop for anyone to pet (I did, but would rather have petted her to be frank), and she drove it home to Disley, I believe, each night in a small Peugeot 304 cabriolet with the top down. That would have been in the early seventies from memory.
Pat Broadhead, a friend who breeds Anatolian Karabash dogs which I too keep, used to have a Himalayan Bear that went for rides out in the car. That was in the sixties. She lives outside Wrexham. Plenty of exotic (and potentially lethal) animals are still kept in the UK by private owners.
The Bear pub not far from me in Hodnet has an original bear pit and it was not THAT long ago that they had a bear that was brought upstairs to amuse the drinkers.
