Pet owning questions!

Hey everybody! Ever since my 5th grade class pet was a leopard gecko I’ve wanted one! I’m finally considering adopting one and I’m super excited!

I’ve done some research on my own but I want to be very prepared before I get one. I was wondering if anybody could give some advice. What are the less known or less talked about things that you wish you knew before you bought a gecko. I want to hear the good, the bad, the expensive, the everything!

Thank you in advance!!
