So I'm trying to get my rescued 6ft red tail use to handling. When I pick her up she doesn't strike but as shes slithering around on me and I keep her away from my face I hear a slight his. Mouthcisnt fully opened. Is this normal? Thanks yall. Btw I only handle her every like 5 days to a week and not after she ate either. Shes been fasting . Handle time around 5 mins.
