green iguana health problem

Question
QUESTION: I've had a green iguana for a 3 years as a rescue I've kept her indoors hoping to find a good home for her, and she's in great health, someone called me and told me about someone who has a great set up with heated habitats small fountains and are outdoors, so i just decided to give her to them, the problem is one of their iguanas has lost many fingers ive never seen this all her scales on her back are gone, and most of the fingers on one hand and several on the other hands they have several iguanas and thats the only one with this problem, they tell me that a vet told them that is mites but I don't believe mites can cause fingers to fall off, my question is is it safe to leave my iguana there? what cause that to happen to that sick iguana? and is it contagious? they are outdoors but there's lots of trees and sunlight peeps through the branches could indirect sunlight be the problem, the heated habitat has a meter and it shows 84 degrees, I'm worried about her, any advice will be greatly appreciated thank you. Joe

ANSWER: Hi Joe,
My feeling is this... if you are not comfortable with this person, then don't leave your iguana there.  I wouldn't.
The set up sounds very nice...what are the temperatures in the heated area during the middle of winter?
Toes are generally amputated from some sort of wire that is used on the cages.  Of course there are other ways, but wire is the most common. Chicken wire is the worst followed by any uncoated wire...  
Yes, mites can cause the problem you saw, but...mites generally attack the folds of the skin, armpits, knees, dewlap, etc. Yes, they can and do attack other parts of the body but there would be damage to the parts I mentioned also.
Burns can cause what you saw as can some other problems such as fungal or bacterial problems.  A viral disease called CANV can also cause the problem, if the iguana survived the disease that is. CANV is highly contagious.  Of course any infection can be passed on to other iguanas.
Ask more questions on their care...diet, supplemental uvb, heat, etc.  Ask for references from vets, other people, etc.   Again, if you don't feel right about this person, then don't leave the iguana there.
