I created this plan to simplify the different stages of hibernation. This plan is based on the information provided by Philippe de Vosjoli in his booklet "Basic Care of Uromastyx". I also used the 1997 Edition of "The Farmers Almanac" to build the second table. The dates of the stages will vary slightly from year to year. This is because they are based on the sun not an arbitrary date. Also in order to make this work it is assumed that your lights are controlled by the sunlight. If not then you must manually adjust the times during the different stages.
This plan has not been tested. Your Uromastyx is your own responsibility, so do not blame me if something goes wrong when you try this plan. If this plan does works for you please let me know.
Thanks.
