I have a Jungle Jag and a Zebra Jungle - one around 2 years old now and the other around 1.5 years. They are both VERY arboreal - rarely do I see them on the ground. When I got my first one, I started with a heat cable beneath the substrate, but after a few months I switched to a ceiling-mounted radiant heat panel. I noticed a significant change in behavioral patterns and increased activity when I switched to the ceiling-mounted heat source. As I've added elaborate backgrounds, vines, plants, etc. to my enclosures, they've used them to the fullest extent. If I give them something new to climb on, they're going to climb on it. They love to hang from stuff and stalk prey at night. Give them some height in their enclosure and some stuff to climb on, and they'll repay you for it. I'm constantly having to run for my camera to catch them in cool poses at night when they become active!
