both post your never lists please
maggie3fan said:I see that green beans are on your ok group...But they should be on the Never list. Beans and any legumes are bad...I am certainly no expert...but I have about 27 chelonia and have learned some things from them. I believe they are all opportunistic feeders and if, for instance, a Sulcata came across a glazed donut in the wild, they would eat it. Does that mean I should feed donuts everyday? Nope, but if I need something to add a little variety to a torts diet I might add the donut.
I was sitting in the sun one day watching a group of Gopherus agassizii I had at the time (a few months old probably 50 grams) when all the sudden one jumped up in the air and took off like a shot...he ran over to the block wall and pulled a bluebelly off the wall. The bluebelly was probably 4 inches and the tortoise 3 inches. It was quite a battle but in the end the bluebelly was eaten all up. In the wild they eat so much more then we allow in captivity...I feed my tortoises everything I can. Don't bother yelling at me, I have already been yelled at by the best, I don't care, I raise healthy tortoises that are well socialized, look good and will eat anything...makes it very easy to take to the Vet and makes it easy to feed and give meds...

This makes calcium oxalate which contributes to stone production. So as well as making the calcium unavailable, it can cause your tortoise to form stones when fed. So you really do have to watch out how much plant material you feed that has an oxalic acid content. I wouldn't feed anything with a medium to high content more than once a week, if that much.
They have done Ca/P ratios for plants we eat, but you will be hard pressed to find data on the ratios of plants we don't eat.

Stones: According to Dr. Mader, etc., it is not the presence of the calcium oxalates that are the main risk in stones, it is dehydration working on the calcium in various forms in the system. Other contributers to stones are thought to be vitamin A deficiency, too much animal protein in herbivores, etc.
Regarding oxalic acid/calcium oxalates- most reports of their contribution to health problems refer to HIGH levels, as are found in rhubarb leaves, deiffenbachia, etc. These reports consider spinach to have a medium level.
Mike Pingleton makes an interesting observation in his new book- we make a lot of comments about the food our reptiles eat that we would NEVER make for human food. You don't skip spinach in your salad because of oxalates, or worry that too much cole slaw is going to give you goiter.
Why don't we worry about this stuff- balance and variety. Good hydration (we are really not as dehydrated as the '8 big glasses of water a day' fadists would suggest), etc.
Why doesn't this work for tortoises? Actually, as far as we can tell, it does.
Ca ratios of non-human foods: It takes some work, but I have found the ratios and other info on a lot of plants that are used in other countries, or that are used for domesticated animals, etc.
The Ca of some hays are:
- Red clover- 3.1:1
- Fescue- 1.4:1
I have not looked for the others, but I will.
