My sav is named Lucy. She (I haven't sexed her yet, but the previous owner thinks Lucy is female, so I'm fine assuming she is,) is uber tame, almost three years old, 32 inches from her snout to the tip of her tail, and weighs in at about three pounds. I adopted her in late August. She is a total sweetheart. I have a couple questions I haven't been successful in finding any worthwhile answers: 1. What exactly constitutes "exercise" for a savannah monitor, and in what frequency would one estimate it should be implemented? I try to give her time out of her enclosure (which is currently way too small for her, but I am looking to rectify that in the near future) whenever I can to explore the first floor of my house, and when I feed her I make her chase her food around and expend some energy (within reason.) Just looking to see if I should be doing more. She doesn't explore with any seeming sense of urgency, but I wouldn't consider her movement lethargic either. 2. I'm not sure what a healthy "girth" looks like for an adult savannah monitor. Does anyone have any criteria or pictures that illustrate where she should be? I want to make sure I am not feeding her too much, or exercising her too little. 3. How long should I expect an adult savannah monitor to take to shed under ideal conditions. Lucy shed her skin on her limbs with no problems or residual buildup. However, it seems the top area of her torso around her backbone and her tail are shedding in little pieces or not at all, unlike her limbs, which came off in a few big pieces. The areas around her shoulders, underside, and ribs seemed to have shed just fine. Just that top part hasn't come off yet. Any insight would be greatly appreciated; and if I need to post pics I will when I get a chance. Thanks.
