The tissue trick is one of the beginning steps during the taming process and is a means for him to get used to your scent. Basically, you get an unscented tissue and place it in your sleeve for a few hours so it will acquire your scent. Be sure that you do not have any scented lotion or perfume on during this time. Then, tear the tissue up into strips and place it into your little one's cage. He will gather it up and use it to for his nest and gain comfort with it. Then, when the time comes for you to actually actively begin the taming process, he will already be a step ahead by being familiar with your scent and know you are a comfort. This trick has given me, as well as many other ham-parents, a lot of help.
