Thanks! I'm not too worried about him shooting blanks, as he wasn't brumated last year but tested with a very high sperm count at the vet anyway at the same time Ma-tsu had her follicles. I likely will brumate them in the future though.
I'm watching them like a hawk! lol!They're going at it as I type this in fact, which I have mixed feelings about as someone pooed while I was out erranding and I want to clean it out. Oy! I do want to get comfortable palpating her. .. hmm... So Neptune will lose interest once she's more obviously gravid? I've seen gravid boas and pythons, they look like they've swallowed a football, colubrids seem more subtle to me. But I'm keeping my eyes peeled!
