re what to gutload with - here are some options (the purpose is to get vitamins and minerals, such as calcium, into the insects in a balanced way, so think about what's in your gutload according to what you want in your chameleon):
The "wet" portion of the gutload, which should be your principle gutload, can frequently includes things like (switch it up with a different couple of items every other week):
dandelion leaves,
squash,
carrot, yam,
orange,
collard greens, papaya, alfalfa sprouts,
mustard greens, pomegranet, kale,
romaine,
hibiscus leaves, fresh
spearmint leaves, cowpeas (blackeyes),
apple, peas, blueberries, raspberries, sunflower sprouts, ... (avoid broccoli and spinach). Fruits and veggies such as these are important both for the nutrients they give (via the insect) to your chameleon, and also because well hydrated prey results in a better hydrated chameleon.
The dry portion (the lesser portion) of a gutload can include (blend/grind fine with a coffee grinder or food processor):
spirulina; dried seaweed/kelp/dulse;
bee pollen; dried alfalfa; organic raw
sunflower seeds; unhulled sesame seeds; hemp seed; dehydrated cranberry powder; beet powder; zucchini powder; kale powder; fig powder; ground almonds; ground brazil nuts; oak leaves; small amounts of quality whole grain cereal (like Kashi or Total); small amounts of oats; small amounts of cracked rye; wheat germ; quinoa; very very very small amounts of skim milk powder; very very very small amounts of powdered egg; high quality monkey chow (read the ingredients); small amounts of avian pellets (read the ingredients, be cautious of too much Vitamin A). Avoid dog food, cat food, fish flake food and other major sources of animal protien and fat.
In my blog, there's a category that will show you what I feed my chameleons on a daily basis.
