The red iguana does not recognize its owner. Red iguanas are a type of lizard and are cold-blooded animals that do not interact emotionally with humans and are not intelligent enough to understand their owner's actions and instructions. If fed for long enough, it will remember the owner's scent and will not attack the owner when the owner approaches.

Precautions for raising red iguanas:

1. Red iguanas need sufficient light. If the light is not enough, red iguanas will suffer from calcium deficiency and loss of appetite. In case of poor health, lack of energy, etc., ensure that the red iguana receives 8-10 hours of light every day.

2. Red iguanas need to take a bath 3-4 times a week, and the bathing water temperature should be around 35 degrees. Taking a bath can help the red iguana shed its skin and stimulate the red iguana to defecate.

3. Red iguanas are vegetarian lizards and can be fed leaves, flowers and fruits of plants, as well as vegetables, fruits, etc. If your red iguana is deficient in calcium, you can feed it some calcium powder to supplement its calcium.
