Found that out VERY quickly and added another couple inches of substrate. Probed her and she is definitely a girl! Forced me into a crash course on Rat Snakes and have LOVED learning all I can. Pounding rats like no one's business, loves to come out to be held, weighed in at 632 grams. She is just an absolute joy to have her in my collection. So much personality, she comes right to me, the burrowing, and the mock rattle with her tail pretending to be a tough rattlesnake.
NEVER in a million years did I ever think a Coulbrid would make their way into my collection as I am a hard core python and boa guy; let alone steal my heart...but she sure has.
Only sad thing is she's in quarantine right now so I don't get to handle her as much as I would like. But I am sure she'll be worth the wait.
Many thanks everyone! I am sooo blessed to have been able to give her her final forever home!
