Iguanas regularly feed on fruits and it is generally considered okay to feed them watermelon, although other types of melon (e.g. cantaloupe) may be a healthier choice. This is because water melons – as the name suggests – are mostly made of water and do not contain many nutrients.
Due to the lower amounts of calories and sugar, watermelon makes for a great fruit choice if your pet needs to be on a diet, or as an occasional sweet treat.

To serve watermelon to an iguana, make sure it is chopped into small pieces and has all the seeds removed. Overall, fruits should make up for less than 20% of your iguana’s diet.
While iguanas can safely consume watermelon, it’s important to offer them a variety of fruits and vegetables to ensure they’re getting a balanced diet. Some other fruits and vegetables you can offer your iguana include apples, pears, bananas, mangoes, grapes, star fruit, peaches, tomatoes, guava, kiwis, melons, figs, apricots, and dates. It’s important to note that fruits should be eaten in small quantities, as they are high in calories, fat, sugar, and salt.
