They're different than balls, totally different continent, but I read in a Carpet Python book that there's a population of carpets at an upper elevation somewhere in Australia where nite temps can drop as low as 36°F and the snakes do just fine.
If people are brainwashed to think that their snake needs to eat every week then when it doesn't, they get all worried. If the standards were updated to be more accurate, and balls only needed to be fed every 4-6 weeks, then people wouldn't be losing their minds when the snake doesn't eat. Lol
