Insufficient calcium or vitamin D3.
Leopard geckos with mild cases MBD can usually be treated at home. Make sure to dust all insect feeders with a calcium + D3 supplement (we recommend Rep-Cal) and leave out a bottle cap full of powder for the gecko to lick from. In severe cases or if there is no improvement after 1 month, veterinary attention is required.
**Note: Unlike other gecko species, leopard geckos lack endolymphatic sacs for calcium storage, so checking their calcium reserves for MBD diagnosis is not an option.**
