Sure, it may be embarrassing, but mistakes are an opportunity to learn, grow, and improve. Everyone makes them.
Yesterday, I made mine, and it inspired this post.
I accidentally left my emerald tree boa enclosure unlocked all night and all day, and I realized when I got home from work. So I decided to put a bamboo skewer through the door hinges to easily remember to keep it shut.
So, what is your biggest husbandry mistake?
