Hi, ive been studying leopard geckos since 2016 but took a year out between 2020-2021 because my gecko died.
i got back into them late 2021 and only just got back into the reptile husbandry side of social media and the internet a few months ago but i’ve come back and everything surrounding sand is so different? it’s wracked my head all day today so i NEED to ask for clarification, is sand now okay for leo’s?
i know in some aspects it’s okay, so i’ll share what so you don’t have to explain them; premade mixes (earth mix for ex) and the topsoil / sand mix. but i’ve seen lots of people say pure sand is fine which is where the confusion has come from. by pure, i mean not added with anything, just dumped into the enclosure straight from the bag. I know other environmental factors will effect and increase / decrease the risk, but surely the type of substrate, or in this instance sand, is an environment factor too, if that makes sense.
Correct me if i’m wrong (please do, it’s why i’m here 😭) but from what i have previously researched and known, sand can cause impaction, eye and respiratory issues, joint issues and possibly even shedding issues. reasons being dusty and dry, unsupportive and that geckos can’t digest it - short version of it; jacobson’s organ, sand expands in liquids (in this case stomach acid) ergo eventual blockage in stomach.

general sands when used alone don’t hold burrow shapes and also being too loose aren’t good for their joints + super dusty
not just sand
