my little eastern garter is wild caught, maybe less than a year old, fed on earth worms, and seems to have some kind of twitch.
i notice when i hold her that she often will start muscle twitching, like a nervous tick or a shudder. it seems to go on for a while and then stop. if i nudge her a bit it might start again.
i'm concerned it might be getting worse.
could this be a neurological issue or a parasite or is this an idiosyncratic twitch of a little garter.
any help would be appreciated. thank you
