:If the rosies are adults I wouldn't even start to get worried yet. I have a sand boa that hasn't eaten since January. I would weigh them to make sure they're not losing weight. I'm not sure what feeding strategies are good for rosies. As far as the corns go, my black rat male is doing the same thing, but he wasn't cooled at all. Go figure!
Neither rosy is an adult-they aren't even a year old yet. I'm just going to try again in a few weeks and see what happens.
