I have a friend I met last year and we both bought snakes together in one order. At that time we were talking about husbandry and he told me how he was only feeding 1 MOUSE to all his snakes a week, regardless of size. Even his adult snakes only got 1 MOUSE about 40 grams, once a week.
I laughed at him a little.
Now, 1 year later, his snakes are all over 1000 grams??? These are 2011 snakes....
He insists that he only fed one jumbo MOUSE per week to each of them, and recently tried rats, once a week, one rat that was 60 grams. That was it.
I know those are the same snakes I bought together with him. They really are all over 1000 grams in one year. He isn't the kind of person to lie about the feeding schedule, you never know but he's not the type.
The snakes I got in the same shipment as his are only about 600 - 700 grams, one is super fast growing at 900+grams, the smallest that isn't feeding too well is still in the 400 gram range. I feed F/T rats that are a lot bigger than mice! Also once a week.
Perhaps we really don't need to feed that much and as long as they are eating regularly, slow and steady is better than eating a lot and going off feed now and then? I know they always eat mice not fussy like when you give them rats.
