Each snake is different. Not all snakes eat with a regular pattern all the time. I would attempt to feed once a week. if your snake doesn't eat that week, try again next week. As has been stated before in other posts, trying constantly to get your snake to eat can cause them more stress than if you just try once a week. The more stressed your snake gets, the less chance you have of getting it to feed regularly. Patience is rewarded when to comes to feeding your pet.
