Tortoise Terrarium, Part 2

I bought a couple more timers last night, and replaced the "desert simulation" fluorescent bulb (it emits UV radiation, to keep tortoise shells hard, or something like that).

Tammy went into her cardboard "cave" without any prompting yesterday afternoon. In my opinion, that makes her multiple times smarter than the dog, who required multiple training sessions over the course of a weekend to understand the utility of the pet door to the back yard (and frankly, sometimes the dog still fails to grasp that it needs to go outside to poop).
