The Minnesota zoo recently saw the debut of lynx kittens (Lynx canadensis), born May 13. Look at the size of those paws (which reminds me of a joke):
Amur leopard cubs (Panthera pardus orientalis) at the Wildlife Heritage Foundation, Ashford, UK (warning: cheesy music).
And a mammal (Felis catus) riding a turtle, or, as the Brits call it, a “tortoise”:
