I Bite Sign

thingiverse

You're warned, a sign on your parrot cage sternly advises everyone to keep their fingers out of there. They'll ignore it, though, because your bird is stunningly beautiful and they can't resist the urge to touch it - until it bites them and draws blood everywhere while shrieking "IT BIT ME! THAT BIRD GOT ME! OMG I'M BLEEDING!". Don't worry, you've posted a clear warning sign on the cage, letting everyone know that your bird is fierce enough to inflict serious injury.
