My female adult Red Tail has dry skin on top, looks and feels somewhat ashy. She is not due for a shed that so far as I can tell. I'm in California and it's rather dry here. I'm waiting on my animal plastics cage to come in and in the mean time have her in a glass enclosure which doesn't hold humidity very well, but I've been misting her cage daily and keeping her water bowl full. Is there anything that can be done to moisturize her skin? Perhaps some pure aloe vera gel from the plant or a natural oil such as almond oil or olive oil?
