Our common lizards are nontoxic. Most lizards eat all kinds of insects and small animals. They basically feed on insects, earthworms, snails and even mice. But this is not absolute, it has something to do with their living environment and species. Some lizards also eat plants, such as iguanas, mainly plants. The only remaining marine species is the Galapagos sea iguana, which feeds on seaweed. Some kinds of lizards live partly in water and eat fresh water.
Lizard's food is also related to local food sources and habits, such as gecko's nocturnal activities, feeding on insects such as Lepidoptera. Larger lizards, such as gecko, can also eat birds and other lizards. Monitor lizards can eat fish, frogs and even prey on small mammals. Even Komodo dragons eat bison, and all kinds of large animals are their food. They are the animals at the top of the food chain in this area.
Lizards kept as pets, such as common green lizards, just wash some lettuce for them to eat, soak it for half an hour before feeding, and then rinse it. If it is not clean, they will refuse to eat it. Some little black lizards, who like to eat bread worms, can buy some bread worms and pour them into food plates. They will hunt by themselves. There are generally three kinds of meat feed for lizards: bread worms, barley worms and crickets. These three kinds of crickets have the best nutrition, and the bread worm is the worst. You can buy more wheat worms and feed them to the lizards at home at any time.
If you only eat insects, it will easily lead to calcium and vitamin deficiency in lizards. It is necessary to add some special nutritional additives to crawling pets. If you raise large lizards, hoses, adult American iguanas, plain monitor lizards, etc. It is best to feed medium-sized mice, and secondly, you can feed some animal viscera and meat, and you should also pay attention to supplementing nutritional additives to make lizards eat nutritious and healthy.
