so when the threads said that they "heard" them rattle they meant they looked like they rattled. i'll see if i can locate the thread. but they said "heard."
i am not worried about anything i am just curious.
My Albino Cali still vibrates her tail, especially when feeding or when spooked. You are bound to hear it at some stage but it's merely a defence mechanism. All my Colubrids do this and yes it does sound remarkably like a rattler!
