Hi I've recently got my first ball python he is 3 month old and I've had him for 8 days he has been left alone with no handling to let him settle into his new home apart from when he had his first meal which was a success with no problems it's been 3 days since he ate. Now I think it's time to start handling him but when I'm going to pick him up he's hissing at me. Before I bought him he was fine when I was handling him in the shop but now he's hissing and has tried striking at me any ideas or tips to help me try tame him down please.
