It might be a little thin and it also could be dehydrated from the look of it.
I feed mine a wide variety of greens (dandelions, kale, collards, endive, escarole, mustard greens, etc.) and veggies (carrot, squash, zucchini, sweet potato, sweet red pepper, celery leaves, etc.) (Sound familiar?? Chameleon gutload!) I also give them a bit of fruit (apple, pear, melon, berries, etc.) and a source of "meat" (cooked chicken, earthworms, crickets, superworms, etc.) Not too heavy on the "meat". I dust the greens and veggies with crushed fruit flavored tums or phos.-free calcium powder at most feedings and twice a month with phos.-free calcium/D3 powder. I provide a UVB light and a basking light.
My cage (water table) has over 3/4 land area and the rest is a pool/pond. I have a drain and tap under the pool area so that the water can be drained and the water area cleaned out almost daily. There are at least two hides....one in the warmer area and one in the cooler part of the cage.
Three toeds can go through a hibernation in the winter and likely need to at least brumate in order to produce good eggs.
