I know this was mentioned before somewhere about tail rattling: but I've recently found out that both my BP and BRB can (and do) vibrate their whole bodies when excited! It's really a weird sensation .... hmm like a vibrator! Since I've had the two in quarantine boxes which are changed every day to deal with the mites, I've noticed things like this a lot more. They don't seem shy or nervous or irritated but they just vibrate sometimes when I reach in to pet them. Talyn is going into shed again... I've also noticed that she smells extremely "musky" lately... is this a hormonal thing, a shed thing, a boa thing or does she just have gas? I never noticed it before, maybe because of the smell of the terrarium soil and reptibark in her usual terrarium. PS -- the Reptile Relief seems to be working... I haven't seen any mites on either snake for at least a week now!
