An adorable, sad little Shar-pei mix named Kai was found tied to a railing inside a Scottish train station last Friday, along with a suitcase packed with all his worldly possessions: A pillow, a toy, and a food bowl with some food. The Scottish Society for the Prevention of Cruelty to Animals is searching for the owner who abandoned him.

Using Kai's microchip, the SPCA tracked down his last known owner. That's where the trail went cold, though, because that person had sold the dog on Gumtree, the U.K. equivalent of Craigslist, back in 2013.

"Regardless of the fact Kai was left with his belongings, this was still a cruel incident and we are keen to identify the person responsible. If anyone can help we would ask them to get in touch as soon as possible," said SPCA Inspector Stewart Taylor.

Kai, who is two to three years old and "a lovely dog with a nice nature," will live with the SPCA until they can find him a new home. If his former owner is ever found, they could be charged under Scotland's Animal Health and Welfare Act and hit with a lifetime ban on keeping pets.
