I have had my baby leopard gecko for a week now and he has not eaten anything. At first his temp in the tank was 80 warm side and 70 cold I jacked the heat up to 90 on the warm side and 75 on the cold. at night the temp is between 70-75 could the cold temperature be causing him not to eat? I have also noticed he is starting to turn white to shed could this also impacting his hunger?
