He's beautiful! One thing though. He's white with blue eyes right? If that's the case, he COULD be deaf, hence the howling. Being unneutered doesn't help either. That needs to be done right away. His youth is in his favor. Please make sure that he gets neutered first. That will guarantee no more babies on HIS part. If you're going to put an ad in the paper, make sure you ask an adoption fee. That will discourage research labs, as they won't pay for strays, from what I hear.
