I was at the Paris Zoo in 2007, and though it was April it was about +26 C and humid. This poor red panda was very hot.

My foster kittens V (the tuxedo) and Santana (the Siamese) trying to beat the heat last summer by napping through the afternoon together. They've now been adopted into their forever homes.
