my old leopard gecko named blizz (we thought she was a blizzard or a lusictictics) used to hiss all the time when we picked her up. she also used to bite my fiance's finger and not let go. we gave her to a pet store because of this is. is this normal for an adult female leo?

my fiance and i went to a pet store 30 mintues from our house to get a 80 dollar jacksons chameleon baby! anyway he is not the main part of the story. the guy also had a baby crestie that had no tail for 40 but it was originally for 80. so we decided to get it and he gave it to us for thirty because we were getting the jackons, but not known to us when he put it in the register he pushed in .30 instead of 30 dollars. so we left and when we checked the receipt later we found the mistake.
