I'm not advocating pinkies, nor am I against them but do have to jump in on some facts. Protein is made of 20 amino acids and one imino acid and all critters are made of a mixture of these. There would be differences such as chitin in the insect and hair on a mammal, both of which are protein structures that cannot be digested, or calcium bone in the mammal and not in the arthropod, etc. But, I cannot see that a pinkie would cause a protein overload vs the same weight of say...silkworms. Once again I don't know if pinkies are good or not, but I just can't see it being from protein overload. There may be something bad in mammals and I think we would all agree that mammals would likely be a rare, occasional snack in the wild. So I will have to say that my gut feeling would be to rarely feed if ever (I don't) but believe as someone has already stated that a well hydrated cham is the best way to avoid excess protein. So, before you lambaste me for not being anti-pinkie, I am not either way, just trying to understand the factual basis for either side.
