Lol, you caught me! Huge Whovian! I actually also have a baby corn snake named Madame Vastra.
Thanks for the heads up on the drainage issue, Strax has spent so little time in his dirt that I've actually had the opposite problem, I'm always misting it to keep it from drying out, so the thought that it could get too wet never occurred to me, lol. How would you suggest I handle it?
