Honestly, I haven't really picked them up and taken a look at their undersides prior to a shed, so I wouldn't know. Right now they're being jerks, as I just tried to pick them up to take pictures to post here, and they're throwing a fit. So I'm going to leave them be for now... as they are both sitting on the place where the heating pad would be with a low heat IR light is on, above them.

I guess the pictures will have to wait.
