My sons bearded dragon is about 9 months old. He started trying to climb the glass about a month ago. I know this is common and is called glass surfing. Our concern is he does it all day long non stop. No longer eats crickets either. Went from eating 20-30 a day. To maybe eating 20 a week. Will eat some fruit and veggies. We had him in a smaller cage, so got him a bigger one thinking that was the reason. That was 3 weeks ago and still the same thing. Any ideas? Nothing has changed since then.
