sand substrate

[bigsnakegirl785]

Actually, impaction is a huge worry, mostly for lizards....many lizards lick things to inspect them, and a lizard licking up sand all day can have it build up over months or even years and die from it. There are a lot of pictures out there with lizards' stomachs full of sand at the time of death. This isn't fake.

Sand also is really bad for causing infections, because it holds in the moisture it's a breeding ground for bacteria, so when a sand grain gets stuck in soft tissue it can irritate the tissue and cause infections. Which can often be deadly.
