What spots can mean.
Yes, stress is possible.
However, attached is a picture of Osama I just took at 5:45 this morning, and like every day, he develops spots on his body when I turn on his heat lamp and he warms up.
He waits by the heat leap each morning at about 5:00 a.m. and gets pissed if it's not on by 5:30 a.m.
He seems to be saying "It's so hard to get good human servants these days."
Heaven forbid I'm late with his breakfast!
