"I'm Kala. This is Keira. We're so scared in here," read the post featuring the picture of Kala with her paws around Keira's neck.

The post made a big impact. It was shared, liked and commented on thousands of times – but most importantly, it found the best friends a new home.

Kala and Keira are still available for adoption. Click here for more information.
