Hey again Joy ... Looks like you found the forum without me. Good job !!! You'll find tons of stuff here ... all you could ever need. As for biting that's usually out of fear (your snake looks pretty docile) or a mistake as in a feeding response. Garters have little teeth kind of like velcro not what you would think in regards to a snake. Fearing a bite is just that ... the fear thing. Most often a garter will musk (poop) on you while trying to escape rather then bite .

Best of Luck & WELCOME
