There is nothing more endearing than seeing true friendship and love. Especially, if it as improbable as that of a big dog and a tiny kitten. Somehow, animals feel when they are dealing with a baby. For example, no matter how much a toddler will tug on the tail of a cat and play roughly with it, it will never or very rarely fight back. This set of pictures taken by Jessie Pon shows a tiny kitten mistaking an adult golden retriever for his mother. Though it may hurt the dog’s nose with its sharp claws, the dog does nothing to harm the kitty. On the contrary, it’s watching over the kitty-cat as if it were her own puppy. (Photo by Jessie Pon)
