What Foods Are Toxic to Bearded Dragons?

Bearded dragons are one of the most popular reptile pets. These creatures are loved for their docile nature and low-maintenance lifestyle. However, just like any other living beings, bearded dragons also require proper care and attention, especially when it comes to their diet. While they can eat a variety of foods, some foods can be toxic to them. Here’s what you need to know about toxic foods for bearded dragons.

1. Avocado

Avocado is a popular superfood for humans and is often included in many diets. However, it is toxic to bearded dragons. Avocado contains a toxin called persin, which can cause severe health issues, including heart failure and death. Feeding your bearded dragon avocado can be fatal, so it’s best to avoid it altogether.

It’s essential to note that other vegetables, fruits, and herbs also contain persin. However, the levels are so low that they don’t pose any harm to bearded dragons. Examples of these include parsley, spinach, and celery.

2. Rhubarb

Rhubarb is a popular vegetable used in pies and other desserts. However, it’s toxic to bearded dragons. Rhubarb contains high levels of oxalic acid, which can bind with calcium and prevent its absorption in the body. This can cause metabolic bone disease, which can be fatal if left untreated.

If you have a bearded dragon, it’s best to avoid feeding it rhubarb or any other food with high oxalic acid content. Instead, provide your pet with calcium-rich foods like kale, mustard greens, and collard greens.

3. Fireflies

Fireflies are not a typical food item for bearded dragons, but they can be attracted to them because of their bright, flashing lights. However, fireflies are highly toxic to bearded dragons. They contain a chemical called lucibufagins, which can cause seizures, liver failure, and death.

If you notice fireflies in your bearded dragon’s enclosure, remove them immediately. Also, ensure that your bearded dragon’s enclosure is free from any insects or pests that can harm them.

4. Wild Insects

Bearded dragons love to eat insects, and they are a crucial part of their diet. However, it’s essential to ensure that the insects you feed your bearded dragon are safe and healthy. Wild insects can be carriers of parasites, pesticides, or other toxins that can harm your pet.

To ensure that your bearded dragon gets safe and healthy insects, you can either purchase them from a reputable pet store or breed them yourself. Also, avoid feeding your bearded dragon insects caught from the wild.

5. Citrus Fruits

Citrus fruits like oranges, lemons, and limes are acidic and can cause digestive problems in bearded dragons. Feeding your bearded dragon citrus fruits can lead to diarrhea, vomiting, and other digestive issues.

While some bearded dragons may tolerate small amounts of citrus fruits, it’s best to avoid feeding them altogether. Instead, provide your bearded dragon with other fruits like berries, melons, and apples.

6. Dairy Products

Dairy products like milk, cheese, and yogurt are not suitable for bearded dragons. These foods are high in fat and can cause digestive problems. Bearded dragons are lactose intolerant, and feeding them dairy products can lead to diarrhea, bloating, and other digestive issues.

Instead of dairy products, provide your bearded dragon with other sources of protein like insects, eggs, and lean meats.

7. Spinach

Spinach is a popular vegetable that’s high in nutrients. However, it’s also high in oxalic acid, which can bind with calcium and prevent its absorption in the body. Feeding your bearded dragon spinach can lead to metabolic bone disease, which can be fatal if left untreated.

Instead of spinach, provide your bearded dragon with other leafy greens like kale, mustard greens, and collard greens.

8. Insecticides

Insecticides are chemicals used to kill insects. However, they can be harmful to bearded dragons if ingested. Insecticides can cause seizures, respiratory problems, and other health issues in bearded dragons.

To ensure that your bearded dragon is safe from insecticides, avoid using them in your home or near your pet’s enclosure. Also, ensure that any plants or food items you give your bearded dragon are free from insecticide residue.

9. Chocolate

Chocolate is toxic to many animals, including bearded dragons. Chocolate contains theobromine, which can cause seizures, heart problems, and even death in bearded dragons.

If you have a bearded dragon, avoid feeding it any food item that contains chocolate. Instead, provide your pet with other treats like fruits or insects.

10. Processed Foods

Processed foods like chips, crackers, and other snacks are not suitable for bearded dragons. These foods are high in salt, sugar, and other additives that can cause digestive problems and other health issues.

Instead of processed foods, provide your bearded dragon with a balanced diet of insects, vegetables, and fruits. You can also provide them with commercial bearded dragon food pellets, which are formulated to meet their nutritional needs.

In conclusion, feeding your bearded dragon a healthy and balanced diet is crucial for its overall health and wellbeing. Avoid feeding your pet any food item that’s toxic or harmful to them. Instead, provide them with safe and healthy food choices that meet their nutritional needs.
