I was recently asked to stabilize some giraffe bone scales (they may be camel -not sure if that matters). Is cactus juice still the right thing to use? Mainly I'm concerned if 200F would cause the bone to crack? I don't think it would, since you can dry bone at 180. I just want to be sure since the customer only has one set of these.....

I have MANY customers who regularly stabilize giraffe bone, antler, and other bone with Cactus Juice with no issues.  I have not personally ever done it so I can not say with absolute certainty that it will not crack.  However, based on the feedback from my customers who are using it for this application, I feel confident in saying you should be fine!
