I built a sunning box for our slider Midori so she can be safely left out on the balcony for periods of basking, which is essential to turtle health. Choco the Cat got into the action, too, but didn’t last too long in the heat.
Note: While we love Midori, and have cared for her for 24 years, we do NOT recommend turtles as pets. Some reasons here in a post on my old blog.
