I volunteer at my local humane society also, and we did a presentation in latchkey on pet care. The school allowed us to bring a dog in for the presentation, so I'm assuming the reptiles would be ok as far as the insurance goes also?

He will be yours, faithful and true to the last beat of his heart. You owe it to him to be worthy of such devotion."-Unknown
