We just got our red knee sling a week ago and it is not eating. We put an ornament in the enclosure and the sling crawled inside of it so we cannot really see it. It's still alive because each time we check the ornament, it is in a different location. We are trying to keep a consistent temp of 75 F. and we mist it every day. The sling is about 3/4 inch long. When we try to feed it, it ignores crickets and mealworms.
