A pet cat in Yantai City, China has adopted a rat and shocked everyone in the locality. Sun Shujun, the owner of the cat said that the rat has been living with the female cat since four kittens were born. The rat not only drinks cat's milk, but also plays with the kittens. It is now the 4th week of their odd relationship and all of them are happy! Similarly last year, a dog in China adopted a piglet.
