Thanks for all the feedback guys! I ended up just reaching in and picking her up and sure enough, she was as tame as a puppy dog. I thought that she may be hungry as the last time this happened, a simple rat did the trick, but I had fed her 3 and she still maintained this behavior. I think that you guys are quite right in saying that it's time I move up in food sizes, she's been growing fast and eating steadily

Once again thank you all for you insight. Cheers
