How Their Bodies Use It

As omnivores, bearded dragons have a flexible digestive system that can handle both meat and plant-based foods. This means their bodies are quite good at breaking down a variety of nutrients. When a bearded dragon eats onions, their body has to decide how to use those specific nutrients. Vegetables like onions provide 'roughage' or fiber. For many small pets, this fiber is vital for keeping their tummy moving and healthy. However, some veggies have specific minerals (like calcium or oxalates) that need to be limited to prevent bladder or kidney issues.

If you decide to give Onions to your pet, here is the safest way to prepare it:
