Hmm... I would say... a 4? :lol: But I've been bit by big macaws so... :stickouttongue: I think lovebirds bite harder because a p'let is more likely to just pinch you and let go, lovebirds will grab and chew. The worst part of a p'let is they ALWAYS seem to go for the cuticles on your fingers! :rofl: I've rarely been bitten so hard that it draws blood by p'lets, tame and untame, it's just a really hard pinch and, like i said, usually on fingertips or cuticles so it hurts because of the location! :lol:
