1963 animal deaths

Syrian brown bear cub found in Iran and adopted by Polish soldiers during WWII

Félicette () was a Parisian cat that became the first feline launched into space on 18October 1963 as part of the French space program. She was one of 14 female cats trained for spaceflight. The cats had electrodes implanted into their skulls to monitor their neurological activity throughout the flight. During the flight, electrical impulses were applied to the brain and a leg to stimulate responses. The capsule was recovered 13 minutes after the rocket was ignited. Most of the data from the mission was of good quality, and Félicette survived the flight but was euthanised two months later
