I wondered about this a lot when I got Gwny. She literally felt like pudding, where my other two BP's feel very firm. I have read that a lot of that has to do with how comfortable the snake is. When she was in blue she felt more firm because she couldn't see and didn't know what was going on. She couldn't kill a rat pinkie by constriction, she actually gave up and started biting its neck really hard and shaking it. I wonder if her issues with constriction has to do with the spider wobble. Though the wrap was fine, just didn't seem to have any power behind it. She is also extremely inactive. Some days I don't think she even thermoregulates, she always feels cooler than the other two. I've been taking her out and letting her roam and climb, so hopefully she will develop more muscle tone.
