I'm planning a new project where we'll be using residual scent on gauze to help imprint a dog on turtles, and I'm wondering how many times a gauze can be frozen and thawed before it should be discarded (that is before the odor degrades). Anyone have advice?
Background: I don't have this species of turtle in captivity but I have a colleague who does and is allowing us to swab his turtles and to train with the live turtles while we visit. We'll be rubbing the gauze on the neck and arms of the turtles (like Cablk and Heaton 2006), and I plan to freeze the gauze for future training sessions. Can we get multiple freezing/thawing cycles from an animal-scented gauze so that we can train with it on multiple days?
