The story of cats in space is a dramatic tale indeed. It begins in an unlikely place with the 1957 Soviet launch of Sputnik 2, carrying of all 
things a dog named Laika. Laika was a stray found on the streets of Moscow who could have been the star of a dandy rags-to-riches shaggy dog story, except that things didn’t go all that well and the pooch perished under mysterious circumstances.
This was viewed as an early skirmish in the superpower space race to which NASA responded by sending a chimp into space and successfully returning him.
The French meanwhile had been plotting their own animal space probe. Fifteen cats had been chosen to undergo extensive training involving centrifuges, compression chambers and other medieval torture devices for a space mission in which the French would prove that they belonged at the table with the big guys and a cat would demonstrate to its fanciers everywhere that cats were superior to dogs in yet another way.
A pretty black and white Parisian chatte was eventually selected for the mission, because she was the only one who hadn’t become overweight during training, something to do with croissants most likely. On October 18, 1963, at 8:09 am, Chatte Félicette boarded a Véronique AGI 47 rocket at a base in the Algerian Sahara Desert and was blasted 97 miles into space. Fifteen minutes later, she parachuted safely to earth and pussycat immortality. Voilà!
