any ideas?

Umm... well...I looked at my bp today and he has like a orange spot on his belly..its a odd shape about the size of a "ok" sign you make with ur thumb and finger...what could it be?

Just a typical variant, no worries.

Unless you have a heat rock in the cage, its probably not a burn....nothing to worry about, I think.

is this the first time you've noticed it? in other words, was it there before or is there any way you could've overlooked it.
