UPDATE: Cat's caretaker found; see comments.
George Morancy reports on a new visitor to his East Boston backyard; hopes the owner of the cat recognizes him:
For the past couple days, this very beautiful male cat has been hanging around in my back yard. There are thousand of feral cats in the city. As a cat lover, I currently live with four happy adoptees, including two from...my back yard.
This cat is a bit different in that he appears to be a Russian Blue. Which would likely mean someone lost him and is searching for him.
