Can iguanas eat spinach?

Spinach is a controversial topic when it comes to lizards in general and iguanas specifically. Spinach is generally considered healthy but unfortunately it can be harmful for reptiles in large amounts so you should only feed it to your iguana in small amounts or avoid it altogether to be on the safe side. Despite being a dark leafy green packed with nutrition, spinach has an extremely high content of oxalates which may bind to calcium and prevent it from being properly absorbed when consumed in large quantities. Calcium deficiency can lead to a variety of diseases from tail rot to metabolic bone disease which is potentially lethal for lizards, and that’s why many iguana owners prefer not to feed spinach to their pets. One cup of raw spinach can contain 700-800 milligrams of oxalates, which is way too high for safe consumption by tegu lizards. Same goes for baby spinach.

Why you shouldn’t feed spinach to your iguana

  • Spinach contains insane amounts of oxalates, a compound that can prevent calcium absorption. Consuming spinach regularly may lead your iguana to experience calcium deficiency or, in the worst case, metabolic bone disease, which is potentially lethal to reptiles.
