Sometimes its not your decision haha. Ask JMCrook about Phyllis haha. His female and my male pretty much set their own schedule. If not fed when they want food, they both just destroy their faces. Caesar split his lip, scuffed up his chin multiple places and messed up a belly scale when I tried to make him wait 14 days for food. It was an experiment and it ended bad. I had to keep him heavily fed for a couple weeks until his scrapes and split lip healed up. And I just checked his belly scale today and it looks fine now too.
Now you might get lucky and get one like Gio and Stern have which aren't so food driven or you might get ones like JMCrook and I have lol.
Retics are pretty darn smart and definitely a different ball game from other snakes. You kind of have to work on their terms and they just kind of accept your terms...sometimes.
