I must admit when I first walked into the reptile store, (Gully Reptile Centa) to buy my first snake, Sprocket, I was VERY scared of getting bitten.... After chatting to the guys there, Andrew in this circumstance, we were trying to work out which snake was best suited to me, I handled Sprocket, (Stimson python) no worries, he was and still is a darling, Andrew then brought out a spotted python hatchling, which was as snappy as anything, and I said to Andrew, no way, way too snappy for me, then i asked should I just let it bite me to experience it and get over it, he laughed and said yes, so I sorta waved my hand in front of the spotted and sure enough, it striked, however, I didn't even feel it..... I was like, is that the best you've got... Lol.....
I ended up buying the Stimson, the first snake I held there, and don't regret it one bit.... Although since we have had him home, I was always very reluctant to get him out of his enclosure, I would always get my husband to get him out, then I would take him from my husband, well last Wednesday, I had no choice but to get him out myself, as I needed to take him back to the Gully reptile Centa to be sexed, so I can double check he actually is male before I bring home my little girl, I found if I put my hand flat in the cage, near him, so he can see me, and slowly move my hand towards him letting him smell me, so he knows it's me, then I get the hook, hook him using my other hand and place him on my hand that is next to him, I have no worries....
I have also noticed that since I have become more confident in myself, he has become more confident in me, if that makes sense, he use to always want to go back to my other half before last Wednesday, now, he loves me, and spends hours sitting with me watching tv, or while I'm on the computer, so I think like most animals, they can sense fear, and hence will be defensive....
But this is just my opinion, which I have hardly any experience only owning him for 2 months and this being my first snake..... But something as a newbie also I have found!
