I fed my BP 48 hours ago and upon picking him up I've noticed that the last 3" of his underbelly has a slight blueish tinted colour to it and it seems a little 'soft'. It's very clear on the white of his belly. On a human I'd describe it as an almost healed bruise. For the four weeks I've had him he's done very well, haven't noticed any problems with him. I did think I'd seen him mildly shake his head just after feeding him last but haven't seen it again. I'm a little concerned as I'd done quite a bit of research before buying and have never come across a blue tint. I'll add a little info incase it's needed. He hasn't stoold for about a week and a half now.
