Glad she's okay Nancy. Funny thing, one of the first stories I heard of a BP getting stuck years ago was in a guy's blue jeans belt loop. Poor guy was a bit upset, he'd just bought those jeans and they were very expensive designer label ones. He too had to cut the loop to free his snake.
We had one of our bigger females, Orlah, do an scary thing the other week. Mike had her out on his lap, his empty coffee cup was nearby. Before we realized what she was doing and fast as a flash, she rammed her head and upper body through the mug handle. It was NOT fun trying to back her out, all the while sweating bullets that she would flex her big body and snap that handle, possibly cutting herself in the process.
I've also had younger snakes get so tangled in my long hair or hair tie that I couldn't get them out myself and had to have Mike work them free. Another reason I love my new short hair LOL.
