My columbian rainbow boa has just recently started refusing food, I've wasted 2 rats so far. Other than that she is very active. I managed to get her to eat ten days ago (I feed her a small-medium frozen/thawed rat every ten days), but it took some time, she usually accepts the prey item right away. I keep a red light on her, from what I understand they cannot see red lights. Is it possible that she is going by the photo period outside and is brumating. If not what else could it be. I keep it 75 degree in the day and 77 at night, there is about a 5 degree thermal gradient in the cage. In the morning a give her a good spray that boosts the humidity up to about 80 percent, then I let it dry out throughout the day. Any ideas?
