How much does he weigh currently? The snakes I want to bulk up I feed every 7 - 10 days an appropriate sized meal. I sometimes feed a little more often, but you will never be able to get it to eat every 5 days like clockwork. That isn’t how it works. You want to use the scale and track her weight. As long as she is eating and gaining weight you are good.
You really need to get a feel for your animal and snakes in general. They seem to go through growth cycles where they will eat and grow at an incredible rate. On the other hand, they may sometimes take long periods where they do not want food. You need to take advantage and make the most of the growth periods without making the snake fat and unhealthy.
I had a 100% het Pied female that shot up to 1150grams and I was hoping to breed last fall. All the sudden sometime around mid-September 2008 she refused to eat. This continued with no food at all, until this March…?
Utlize the scale, observe & learn through trial and error and most of all be patient.
