Everything marked in gold lettering are the exact supplies we use in our babies' enclosures. Everything marked in grey lettering is what we recommend as another option.
Sterilite shoe box with ventilation (more information on ventilation here)
Paper towel sheets (for substrate)
Decorations (egg cartons, toilet paper rolls, fake leaves, pipe insulators, etc)
Pangea food and live insects (small/medium mealworms, small/medium crickets, and/or medium dubia roaches [live insects are highly recommended for crested geckos])
Feeding cups (we use water bottle caps, but you can also use small gecko feeding cups)
(optional) Thermo/hygrometer (digital)
