Luckily not from one of my garters However my rescued redbelly snake (storeria occipitomaculata) continues to act strange.

Here's the timeline; she was in captivity for a week before I got her, but ate nothing. Two days after I got her she ate one good size slug. At that point I figured I could stop worrying about her. But it's been over a week since then, and she hasn't taken any more food.

If I had a young garter her size, I'd be feeding it every day (which is why I'm getting a little paranoid). She doesn't seem to be losing weight, so I'm not panicking just yet. Am I expecting the wrong sort of metabolism from her? Like... Size-wise she looks like she should be fed every day, but age-wise she's probably between 7-9 months old, so should maybe be able to go longer without food. Not sure which 'rule' to go by here. I've been offering slugs and cut-up nightcrawlers nightly.
I would try small earthworms, but there is nowhere nearby that I could fine any (they spray the grass around my apartment a LOT).

Also, I don't believe this is a case of captivity stress. Whenever I check on her, she is perched on her vines, looking around. If I go up to the tank, she'll follow me around through the glass tongue-flicking. She's also very calm when being handled (I have to put her in a small tupperware container to feed since I'm offering slugs). No acting sick either.
I've tried keeping her both in my bedroom (65-70 degrees) as well as the reptile room (75-85). Right now I've been keeping her in the cooler room during the day and the warmer room at night (we sleep with multiple fans running, and it just seems like that could bother her...). She doesn't seem any more or less active in either room.

Any suggestions for what else I can do? I'm considering placing her tank beside my baby garter's and letting her watch him feed. They're close to the same size. Maybe it'll make her more competitive... I'd really like to keep her till spring when she has a better chance being released.
