Feline Care described Brian as "handsome" and "mature." If no one steps up, they'll begin the process of finding him a forever home - but they're hoping he has a family somewhere out there looking for him.
"We're hoping that he's not another dumped pussy cat and that he's just got himself lost," Feline Care said. "He's obviously very distinctive with his extra little ear so someone must be missing him or recognise him."
If you're in the area and have any information about Brian's owners, you can contact Feline Care at firstname.lastname@example.org . If you're not and you'd like to add a cat to your home, you can visit Adopt-a-Pet.com to see needy cats near you (Disclaimer: Most of them have two ears).
