They can, but it depends on the weather, and how it cycles where you are. Also if your animal was wild caught then this can change a lot of how it acts/feeds durign the cooler months. East coast, and west coast animals tend to act differenly during the winter. I do not brumate my frills because I am in southern cal, and it rarely gets lower than 55 at the worse. Hope this hepls...
