It's his birthday color "Halloween Pumpkin".
He's worn two collars since the vet decided his bday was Halloween. He was only just 4 months old when I rescued him.
He is my little "man" and picked his own name by not responding to any other names I tried on him. Charlie means "free man." It's English German for Free Man strong.
Well, he is that. Roflol!
