You have moved or redirected all the pics and we can no longer see them..

You apparently know what your doing so just make sure the boa's husbandry is correct. Keep a close eye on her and feed her slowly. Boa breeders will tell you they always do best and build more muscle mass, as opposed to just fat, when fed smaller prey or less often. If she was underfed just start out a little smaller than what should be expected for a boa of that size and work her up. Once she is of a healthy weight she should do good on about 2 to 3 feedings (oppropriatly sized) per month given her age.

Keep her seperate from any other reptiles for a few months or so and post us some pics in about a month after she shows improvement.

Good job on the rescue. In essence thats what you did. Its better she went to you than someone who knew nothing about them and only wanted a "cool" pet to look at.
