What Do You Feed a Pet Lizard?
Feeding your pet lizard is all about understanding its specific dietary needs, which vary wildly by species. Most pet lizards are either insectivores (eating insects), herbivores (eating plants), or omnivores (eating both). Getting this wrong can lead to serious health issues, so knowing what your particular reptile friend munches on is absolutely essential.
You might be wondering if your bearded dragon eats the same things as your gecko, or if your iguana needs a salad bar. We found that diet is one of the most important factors for a lizard’s health and longevity. It impacts everything from their energy levels to their immune system and even their behavior. It’s not a one-size-fits-all situation!
- Most lizards eat insects, plants, or a mix.
- Diet depends entirely on the lizard species.
- Proper nutrition is key for lizard health and happiness.
- Incorrect food can cause serious problems.
- Always research your specific lizard’s needs.
So, let’s get down to what you should be putting in your lizard’s food bowl – tailored just for them!
Feeding Your Lizard: A Species-Specific Guide
The best food for your pet lizard depends entirely on its species. You can’t just grab a bag of generic “lizard food” and expect it to work. Understanding your lizard’s natural habitat and diet is your first step. Many common pet lizards fall into three main categories: insectivores, herbivores, or omnivores.
Insectivores: The Bug Eaters
If you have a gecko, chameleon, or many types of skinks, you’re likely dealing with an insectivore. These lizards thrive on a diet of live insects. Think of it as a natural hunting experience for them! For chameleons, a specialized chameleon diet guide is available.
What Kinds of Insects?
Crickets are a staple for many insectivorous lizards. You can also offer mealworms, dubia roaches, and waxworms. However, not all insects are created equal. Some, like waxworms and superworms, are high in fat. It’s best to offer these as occasional treats rather than daily meals. You want a good variety to ensure your lizard gets a range of nutrients.
Gut-Loading Your Insects
This is a super important step many new owners overlook! Gut-loading means feeding the insects a nutritious diet a day or two before you feed them to your lizard. This transfers those nutrients directly to your pet. Offer the insects fruits, vegetables, and specialized gut-load formulas. Research shows this can significantly boost the nutritional value of the insects (University of California Davis Veterinary Medicine).
Dusting for Success
Most insectivorous lizards also need calcium and vitamin supplements. You’ll want to dust the insects with a calcium powder a few times a week. A multivitamin powder can be used less often, perhaps once a week. Always follow the product instructions carefully. Too much of a good thing can be harmful, too.
Herbivores: The Plant Lovers
Species like iguanas and uromastyx are herbivores. They need a diet rich in leafy greens and other plant matter. Forget the bugs entirely for these guys!
What Greens Are Best?
A good base for many herbivores includes dark, leafy greens like collard greens, mustard greens, and dandelion greens. Romaine lettuce can be offered, but it doesn’t offer as many nutrients. You can also include small amounts of other vegetables like squash and carrots. It’s a good idea to chop everything into bite-sized pieces.
Things to Avoid
Some plants are toxic to lizards. For example, spinach and kale can bind calcium, making it hard for your lizard to absorb. Avoid feeding onions, garlic, and avocado, as these can be poisonous. Always double-check any plant before offering it to your herbivorous pet. Many reptile care guides list safe and unsafe plants.
Calcium and Vitamin D3
Herbivorous lizards often need calcium supplementation, especially if their diet lacks variety or if they don’t get enough UVB light. Vitamin D3 is crucial for calcium absorption. Many reptile experts recommend a calcium supplement with D3 a few times a week. Check with your veterinarian for specific dosing.

Omnivores: The Best of Both Worlds
Some lizards, like bearded dragons, are omnivores. They eat both insects and plant matter. This gives you a bit more variety in their diet, but you still need to get the balance right.
Balancing the Diet
For bearded dragons, their dietary needs change as they age. Young, growing dragons need more protein from insects. As they get older, they need more greens. A general rule of thumb is that young dragons should eat about 80% insects and 20% greens. Adult bearded dragons should eat about 80% greens and 20% insects. Always offer a variety of both.
Safe Foods for Omnivores
For insects, offer crickets, dubia roaches, and mealworms. For greens, provide dark leafy greens like collards and mustard greens. You can also offer small amounts of fruits and vegetables like berries, bell peppers, and sweet potato as occasional treats. Remember to gut-load insects and dust them with supplements, just like you would for an insectivore.
Special Considerations for All Pet Lizards
No matter what type of lizard you own, there are a few universal feeding tips to keep in mind. Clean water should always be available. Many lizards prefer fresh water daily in a shallow dish. Some arboreal species may need their water misted onto leaves.
Staple Foods Checklist
Here’s a quick checklist to ensure you’re on the right track:
- Identify your lizard’s species and its natural diet.
- Research specific safe food options for that species.
- Offer live, gut-loaded insects for insectivores/omnivores.
- Provide fresh, dark leafy greens for herbivores/omnivores.
- Supplement with calcium and vitamins as recommended.
- Always ensure fresh, clean water is available.
When in Doubt, Ask a Pro
If you’re ever unsure about what to feed your lizard, don’t guess! Your veterinarian or a reptile-specific breeder can provide the best advice. They have extensive knowledge about reptile nutrition. They can help you create a feeding plan tailored to your specific pet’s needs.
Conclusion
You’ve learned that feeding your pet lizard isn’t a one-size-fits-all task. It truly depends on their species – whether they’re bug-loving insectivores, leafy-green herbivores, or a mix of both like omnivores. Getting their diet right ensures they live a long, healthy, and happy life. We found that paying attention to gut-loading insects, dusting them with supplements, and choosing the right greens is key. Your next step is to confirm your lizard’s exact species and then consult a trusted reptile resource or veterinarian to fine-tune their personalized meal plan.
Frequently Asked Questions
How often should I feed my pet lizard?
Feeding frequency varies greatly by species and age. Younger lizards, especially omnivores and insectivores, often need to eat daily. Adult herbivores might eat less frequently. Always research your specific lizard’s needs or ask your vet for guidance on appropriate feeding schedules.
Can I feed my lizard the same thing every day?
Offering variety is generally best for your lizard’s health. A consistent diet of only one or two items can lead to nutritional deficiencies or imbalances. Aim for a diverse range of appropriate insects and plant matter to ensure they receive a broad spectrum of nutrients.
What kind of water dish is best for my lizard?
Most lizards do well with a shallow, sturdy water dish that’s easy to access and clean. Some arboreal species may prefer their water misted onto leaves, as they may not readily drink from a bowl. Always ensure the water is fresh and clean daily.
Are store-bought “lizard foods” a good option?
While some commercial foods can be a supplement, they are rarely a complete diet on their own. Many experts recommend focusing on whole, natural foods like live insects and fresh greens. If you do use commercial products, research them thoroughly and use them in moderation as part of a varied diet.
What are signs my lizard isn’t eating enough?
Signs of poor appetite can include lethargy, weight loss, sunken eyes, or a dull appearance. If your lizard stops eating or shows a significant decrease in appetite, it’s a serious concern. This often indicates an underlying health issue or a problem with their diet or environment, so consult your veterinarian promptly.
