One of my adult male snakes really hates my girlfriend. He has bitten her once, and made several other attempts to bite her. He is fine with me, very sweet and he has never shown any aggression towards me at all. I have even seen him hiss as she walks past his enclosure.. My female snake loves her, my other male is fine with her too. I was holding him this morning and he was fine...as soon as he saw her he pulled back as if he was going to strike. She has never mistreated him in any way. What do i do?
