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.
This is my Leopard Gecko, Nova, sitting in the shade on a summer day.
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.
