I handle my animals day 1 if they are receptive. If they are explorative and using their tongue to smell around, if they aren't in a defensive etc. I read my animals very well after so many years of working with them. Some snakes need a week or two to feel safe and adjusted. Remember you don't play with a snake. You support them and give them security for the world. If you can make them feel safe day 1 do it. I have had my lesser enchi female for 3 weeks and I could tell day 1 she needed her own time. I gave it to her and she is amazing now. The other 30+ snakes were all handled day 1 then ate day 3 no problem. Be calm. Be supportive. Move slow but with conviction. Don't hesitate and worry about your Animal. It makes them worry. I think they can feel our vibration from our soul. My animals know on some molecular level I am their security. Because I broadcast that feeling with my whole being.
