These adorable Sumatran tiger cubs were born at the San Diego Zoo Safari Park. They groom each other just like kittens. The keepers handle them to desensitize them to human touch while giving their tiger mother a short break.
The zoo says "Keepers give their mother short breaks from the cubs to stretch her legs and get a little sun while they take the opportunity to socialize with the cubs. They are being desensitized to human touch in anticipation of vaccines and other necessary veterinary care."
The cubs have the cutest expressions on their little faces. take a look:
