Here's my Boaphile setup (48x24x18) w/ awesome Quest Hides for my Irian Jaya Blue Tongue Skink. My skink uses the ramps on the hide no problem. I had to 'train' her to use it by placing bits of leftover Thanksgiving turkey in a path up the ramp. Thanks for looking!
And here's my bluey soon after I put her in her new cage. I think she was overwhelmed.
