Any advice on how to get a skittish, wild-caught garter over to frozen pinkies? Had him for about five months, just started handling a few times a week this week at advice of another snake owner. He's been kind of on-and-off food - ate only half a nightcrawler last week after not eating for 3 weeks. He was interested in a pinkie, but gets scared by my movement. Is the solution here to just handle him more/get him less scared of people? In the past, I've just been leaving nightcrawlers on a paper towel, and if they move enough he'll go for it, but I'd like to get him to mice.

EDIT: Here are some photos. He's about 27 grams right now. Looking healthy?
