Miss Hissypants is suffering from pre-molt syndrome. As I filled her water dish, she unexpectedly lunged toward me and slapped my hand with surprising strength. She then held this threat pose for several minutes.
A couple days post-molt. I know these guys are sexually dimorphic, where the males grow little or no horn. The molt was inconclusive as it was a little too torn up, but by this size (right around 2", molt measured 1.75" stretched DLS) shouldn't the horn be bigger/more defined on a female?
