Any citrus fruit (except
lemons, as they are to bitter!)
Baby food many be fed to sick reptiles or reptiles on hunger strikes. However, it is never advisable to force feed an animal unless absolutely necessary, as it causes tremendous stress. Baby food also has an unbalanced calcium/phosphorous level, which is unhealthy for chameleons, therefore should never be offered as the sole nutrient for a prolonged period of time. It also makes your chameleon lazy and they may stop hunting on their own. They also tend to become very poor hunters after being hand fed (they loose the ability to aim and coordinate their tongues). All fruit baby foods however, are good, like applesauce, carrots for beta-carotene and blueberries! There are techniques to feed your unreceptive chameleon insects if necessary (contact me to discuss).
Your vet may recommend special cat food instead of baby food. Keep in mind as well that you want to select a baby food that is high in protein like; veal, beef and broth. My chameleon always loved ham and egg casserole! To add extra protein, you can buy dried flies (in the fish section of your local pet store) and grind them up with a mortal and pestle and mix them in the baby food. You may want to add a small amount of liquid calcium (calcium sandoz) to thin out the mixture!
