Thank you everyone. I'm amazed at how much I've enjoyed watching Dash crawl around and explore his new home. I did notice, however, that the opening on his hot hide (the one with the stairs) was too large and it didn't seem to get dark enough during the day. I decided to modify it by closing up the opening with spray foam, regrouting and resealing. I'm pleased with how it turned out.
Very cool. Good call on the warm hide. I'm constantly fighting with store-bought caves and trying to make certain too much light isn't shining into them... maybe one of these days I'll get ambitious enough to try constructing some of my own. Excellent work!
