Had my Russian 2 weeks, she has no heat mat no heat night she has lots right heat day, she sleeps when we do, she had just settled and seems happy. I want to hibernate her outside this winter, I am learning also she is 2 or bit older, good luck
After advice this is her new home, new heat more substrate, new water bowls, for her age table top is adequate until warmer weather as sought advice, not perfect but transformer, and she is happy and responsive it seems
