Alternatively, 'a virgin shall conceive'.

We weren't, and still aren't, planning on breeding ours. Steve's a bachelor and when we took Fuzzy in, she(I suppose!) came with her own vivarium. It was all fine we decided.

Then, we started seeing stuff in Fuzzy consistent with what people describe in snake ovulation. The 'glow', the shed, the 'tail suck' (big and bad), and my first thought is 'only mammals have estrous cycles, Steve has been nowhere near her, her previous owners totally bred her without telling us, goddammit', and that sort.

...But I don't know. See, all the resources on this deal solely with mating so of course all those females involved are gravid.

...My question is, if this snake is ovulating, does it mean she's gravid? Obviously they don't produce clutches of unfertilized eggs like chickens and obviously they don't have an estrous cycle, so...just how DOES this work?
