What Do Lizards Eat (Diet, Care & Feeding Tips) – Reptile-Guide

Lizards are ancient reptiles with thousands of species living across the world. They have been around for millions of years and have evolved to survive in a wide range of habitats. With their unique qualities, lizards make great pets and can be quite fascinating to observe. But what do lizards eat? The answer depends on the type of lizard you own or are interested in owning.

Types of Lizard Diets

The diet of a lizard depends on its size and species. Generally speaking, lizards fall into categories based on their diets such as insectivores, herbivores, omnivores, carnivores, and nectarivores.

Insectivore Lizards

Insectivore lizards include a variety of geckos, skinks, chameleons, and anoles. These types of lizards will feast primarily upon insects such as mealworms, crickets, flies, and other small bugs. These should be offered daily as part of their main food source as they contain important proteins and nutrients that will help keep your pet healthy and active.

Herbivore Lizards

Herbivore lizards include iguanas, tegus, and some types of geckos that eat plant material instead of insects. A varied diet composed mostly of leafy greens is essential for these types of lizards with occasional vegetables like carrots or squash added for extra nutrition. Some herbivorous lizard species will also require special dietary supplements to ensure they receive enough calcium in their diets since leafy greens don’t contain enough on their own.

Omnivore Lizards

Omnivorous lizards such as monitors eat both plants and animals in the wild so it’s best to offer them a combination meal when at home consisting mostly of smaller insects along with some chopped vegetables like kale or red bell peppers for additional fiber content. Mealworms are also a great option for omnivorous lizards since they provide both proteins from the insect itself plus fiber from the shell which helps aid digestion healthily.

Carnivore Lizards

Carnivorous lizards such as Gila Monsters or Bearded Dragons should be offered whole prey items such as mice or baby chicks along with occasional treats like cooked eggs or beef hearts every other day or so if desired by the owner. Whole prey items are important since they provide beneficial vitamins like B12 that help keep a carnivorous lizard’s organs functioning optimally while helping them maintain proper weight levels too!

Tips For Caring For Your Lizard’s Diet

Once you know what type of diet your lizard needs it’s time to create a plan for feeding them properly.

  • Offer appropriate-sized meals based on your pet’s age – baby lizards need smaller portion sizes than mature adults – so make sure to adjust accordingly.
  • Vary the food you offer your pet throughout the week – this helps ensure they get all the different nutrients they need.
  • Never feed live prey items like mice or crickets to your pet unless you’re sure it is safe.
  • Always wash all fresh produce before offering it to your pet.
  • Monitor how much food your pet eats during each feeding session so you can adjust portions accordingly if necessary.
  • Make sure any supplements added to your pet’s food are given in recommended doses only.
  • Remove any uneaten food from the enclosure after each feeding session.

Common Mistakes to Avoid When Feeding Your Lizard

When it comes to feeding your pet lizard, it’s important to make sure you are doing the right thing for their health and wellbeing. Making mistakes when feeding your lizard can have serious health implications, so here are some of the most common mistakes to avoid when caring for your scaly friend.

Not Researching Proper Nutrition

One of the biggest mistakes you can make when feeding your lizard is not researching proper nutrition. Every species of lizard requires its own unique diet to stay healthy, so be sure to look into what type of food works best for your particular species. For example, green iguanas should eat a variety of dark leafy greens such as collard greens, turnip greens, and dandelion greens. If you’re unsure of what kind of food is best for your specific lizard, speak with a veterinarian or another reptile specialist who can help provide guidance on the subject.

Not Checking Food Freshness

Another mistake to avoid is not checking the freshness of the food that you feed your lizard. Old or spoiled food can contain harmful bacteria or toxins that could make them sick. Be sure to check expiration dates on packaged foods, and inspect all fresh fruits and vegetables before giving them to your pet. If you see any signs of spoilage or mold, do not feed it to your lizard.


It’s easy to overfeed a pet lizard since they can often seem like they’re always hungry! However, overfeeding a pet lizard can lead to obesity, which in turn can lead to other health problems such as metabolic diseases and joint pain due to extra strain put on their bones from carrying too much weight. Make sure that you keep track of how much food you feed each day and stick within recommended guidelines for their species based on their size and age.

Feeding The Wrong Types Of Food

Lizards need certain types of foods in order for them to get all the nutrients they require for good health. Some lizards may enjoy certain human foods like cooked pasta or rice but these should only be occasional treats rather than part of their regular diet as these kinds of foods are not nutritionally balanced enough for a reptile’s needs. Be sure that everything that goes into their diets should be specifically made or approved by veterinarians specifically for reptiles – no exceptions!

Not Providing Appropriate Environments For Eating

When feeding lizards it’s important that they have an appropriate environment in which they feel comfortable eating; this includes avoiding too much light exposure while they eat as well as having places where they feel safe from predators. Additionally, if there are multiple lizards being kept together in one habitat then it is essential that separate areas are provided where each one can separately consume their food without any competition from others in order to ensure each one gets their fair share without anyone feeling intimidated by other members in the enclosure.


Properly caring for a lizard’s diet is essential for keeping them happy and healthy throughout their life! Knowing what type of foods to offer based on species can be difficult but following these tips should help make things easier as well as more enjoyable for both you and your reptile friend.
