I feed all my snakes outside in a separate feeding tub just bc i get a very strong feeding response...when they go in there they know its time to eat. My suggestion is to pick up a digital scale for 35$ mice/rats can be seen as small to some but when you put em on the scale theyre huge... My buddy was feeding his snake 30-40g rats at 3-4 months old bc he had no clue how big to feed... snake was pounding em with no problems but once he got a scale and found out how much they really weighed hes was very surprised.
