Lots of people use Hibiscus and Pothos plants in the cage. Chams can happily eat these. Dandelion leaves are good. Strawberries are often a Veileds favourite fruit. Anything that goes into a gutload can be fed to them. Having said that my Veileds don't like fruit or veg at all (they have eaten a bit of strawberry but not the last few times I offered it - more for me though ) https://www.chameleonforums.com/blogs/sandrachameleon/75-feeder-nutrition-gutloading.html
