Hello Myles,

Thanks very much for the kind words.

There are variations of the basic diet that work well, but not much information as to details - "how much squash is too much", .etc. Iguanas have evolved to feed primarily upon leafy greens as opposed to vegetables, so providing a variety of these, is the safest route to go. The diets I've used for iguanas and related lizards generally included squash, zuccinni, etc on a regular basis, but in small amounts.

However, given that the animal is 11 and in good health,I hesitate to recommend much of a change (I once ran into a zoo visitor who fed her red eared slider candy and mints as daily treats - I was about to lecture her, but resisted when I learned the animal was 41 and had bred repeatedly!...many such stories). I would begin slowly introducing a variety of other greens such as those mentioned in the article and perhaps gradually cut back a bit, not drastically, on squash. Major, sudden changes could cause more harm than good, upset the digestive system, etc. Assuming there's been no major health problems, you are safe in continuing more or less as you have been.

Thanks again for your thoughts...please feel free to post on my blog as well, when you have a chance, Best, Frank
