So, full disclosure, this isn't actually for my beardie but a large female python. She's just getting out of her quarantine bin and I'm having trouble finding a UTH that's suitably sized for her permanent enclosure. Anyone have suggestions? I'm looking for something roughly 12 by 18 inches, though obviously a little different than that isn't going to hurt my heart.
