What Do I Feed a Lizard? A Complete Guide to Lizard Diets

If you're a lizard owner, understanding what do I feed a lizard is crucial for ensuring your pet's health and well-being. Lizards are a diverse group of reptiles, and their diet can vary significantly depending on their species, size, and natural habitat. From leafy greens to insects and even small mammals, the correct feeding regimen is essential for maintaining a happy, healthy lizard.

In this article, we’ll explore the types of food different lizards eat and provide guidelines on how to care for your lizard’s nutritional needs. Whether you're wondering what do I feed a lizard for your pet gecko, bearded dragon, iguana, or other species, you’ll find the right information here.

What Do I Feed a Lizard? General Feeding Guidelines

The diet of a lizard depends on its species. Most lizards can be classified as either herbivores, carnivores, or omnivores. Here’s a breakdown of the primary food types for each category:

1. Herbivorous Lizards (Plant-eating)

Lizards that fall into this category eat a variety of plants, fruits, and vegetables. Some of the most common herbivorous lizards include the green iguana and the uromastyx.

Foods for Herbivorous Lizards:

  • Leafy greens: Kale, collard greens, dandelion greens, and mustard greens are excellent sources of fiber and nutrients.
  • Vegetables: Squash, zucchini, carrots, and bell peppers provide essential vitamins.
  • Fruits: Apples, berries, papaya, and melons offer sweet treats high in vitamins like vitamin C and antioxidants.
  • Herbs: Parsley, cilantro, and basil can be offered as safe, flavorful options.

Be sure to offer a variety of greens and vegetables to ensure your herbivorous lizard gets a balanced diet. Avoid iceberg lettuce, as it has little nutritional value for lizards.

2. Carnivorous Lizards (Meat-eating)

Carnivorous lizards, such as the Komodo dragon and certain species of monitor lizards, feed primarily on animals. These lizards may consume insects, rodents, or even other reptiles.

Foods for Carnivorous Lizards:

  • Insects: Crickets, mealworms, waxworms, locusts, and superworms are common insect food for carnivorous lizards.
  • Rodents: Some larger carnivorous lizards, like the Komodo dragon, may feed on small mammals, such as mice, rats, and even larger prey.
  • Other reptiles: Some species, particularly monitors, may also eat smaller reptiles.

Ensure that any insects you offer are appropriately sized for your lizard’s age and size. Additionally, if you are feeding live prey, be aware that it must be properly gut-loaded (fed nutritious food) for the lizard to get the full benefit of its nutrients.

3. Omnivorous Lizards (Both Plant and Animal-eating)

Many lizards, like the bearded dragon and crested gecko, are omnivores. These lizards eat a mix of plant material and animal protein, giving you the flexibility to feed them both veggies and insects.

Foods for Omnivorous Lizards:

  • Vegetables: Offer leafy greens like kale and collard greens, as well as vegetables like bell peppers, carrots, and sweet potato.
  • Fruits: Berries, bananas, apples, and mangoes are great for added flavor and nutrients.
  • Insects: Crickets, roaches, and mealworms are good sources of protein.

It's essential to offer a combination of plant and animal-based foods. For omnivores, balance is key, so try to include a variety of food types to meet all their nutritional needs.

What Do I Feed a Lizard Based on Size and Age?

Lizard dietary needs vary depending on their age and size. Hatchlings and juveniles generally need more protein to support their growth, while adult lizards may require fewer insects and more plant matter.

Hatchling and Juvenile Lizards:

  • Carnivores: These lizards should be fed primarily insects, with an emphasis on small, soft-bodied prey like pinhead crickets or fruit flies.
  • Herbivores: Young herbivorous lizards, like iguanas, should be offered softer greens and finely chopped vegetables.
  • Omnivores: Juvenile omnivores need a high-protein diet, so feed them a mix of insects and plant material.

Adult Lizards:

  • Carnivores: As they mature, carnivorous lizards will continue eating insects or small mammals, but the amount of protein should be reduced to prevent obesity.
  • Herbivores: Adults need a consistent diet of leafy greens and vegetables. Avoid feeding them too much fruit, as it can cause digestive issues.
  • Omnivores: Adult omnivores still require a mix of vegetables, fruits, and insects, but the frequency of insect meals should decrease.

What Do I Feed a Lizard? Special Considerations

  • Vitamin and Mineral Supplements: Lizards often require calcium and vitamin D3 supplements to maintain bone health and prevent metabolic bone disease (MBD). This is especially important for herbivorous lizards.
  • Water: All lizards need fresh, clean water. Some species, like the bearded dragon, prefer to drink from a shallow bowl, while others, like geckos, may drink droplets from leaves or a misted enclosure.
  • Feeding Frequency: The frequency of feeding depends on the species and their age. Younger lizards usually need to eat more often, while adults can often go a few days without food.

Common Foods to Avoid Feeding Your Lizard

Not all human food is safe for lizards. Here’s a list of foods to avoid:

  • Iceberg lettuce: It has low nutritional value.
  • Avocado: This is toxic to many lizard species, including iguanas and bearded dragons.
  • Citrus fruits: The acidity can upset a lizard's digestive system.
  • Dairy products: Lizards are lactose intolerant and cannot digest dairy.

Conclusion: What Do I Feed a Lizard?

In summary, what do I feed a lizard depends largely on its species, age, and dietary classification (herbivore, carnivore, or omnivore). Understanding your lizard’s nutritional needs is key to keeping it healthy and thriving in captivity. By providing the right balance of plant material, protein, and supplements, you can ensure your lizard lives a long, healthy life.

Always research your specific lizard species to know the best foods for them and consult with a reptile vet if you're unsure about their diet. With proper care and feeding, your lizard will stay happy and healthy!
