That possibility had occurred to me as well...its happened before and it will probably happen again when one relies on someone else to sex snakes..LOL. The smaller animal that was almost killed has no visible spurs (unlike the larger obvious male) ans probed only 3 rows deep...barely getting the probe in the vent basically..and I used 2 different diameter probes to be certain.

Would 2 males all of a sudden fight for dominance w/there never being the presence of a female? Its just wierd that all of this started right after a cage change.
