I agree with Mykee....Jake and Sunny come out when I want to play with them. I usually just hold them, and let them crawl around on arms, hands or necks, and I check 'em over after shedding to make sure they shed completely. I also like to "know" my snakes. so if something changes, I can tell pretty quick.
I think that breeders and pet owners handle their snakes differently. What is considered "handling" by a breeder is probably different than "handling" by a pet owner. If you have 20 or 40 snakes, you probably aren't going to take each of them out to play with it every day, for any amount of time. They sit in a sweater box, and maybe retain more of their "wild" state than a frequently handled pet ball. I handle my snakes after feeding because they are out of their cage, and I have never, ever had an animal regurgitate it's meal. Most of the time, they don't want to go back IN the cage. It's all in what they get used to.
