Stephen & King are very close (bonded) brothers. Stephen is on the left in the picture - he has a white spot on his back. King has more black under his eyes (and everywhere).
They are wonderful, friendly lovebugs. Due to recent meds King is a bit more standoffish than Stephen but is getting back to his normal self. They both love being up high and teasing you as they hang over you. Stephen will also get behind you and pull hair if you aren't paying attention at the correct moment. They love to play together although both can be rough. They are the best boys!
