No chart really. Feed an appropriate sized meal every week or so and let the snake tell you if it's enough. If they push like crazy and your husbandry is fine then they're probably hungry or want to breed. My kalatoa girl beats her face up pushing at the doors if she isn't fed every 6 days but she's due for a substantial increase in prey size. Giving her two xl rats tonight and hopefully she'll go a full week without issue.
