:I think the Vision cages are perfect. The 332 is a perfect size and is lockable. I use Dr. Seward's advice and have my cage near a window to provide ambient lighting. Heating is best with a heat pad under the cage. If you are even considering getting a gila, buy Dr. Sewards book. It's a must. : Do you use any lighting on the cages. Being desert animals, do they require any uvb bulbs, or full spectrum lighting? Do you use overhead heating, or mats under the cage? THanks!
