When we have guests our sulfur crested Too climbs down from his perch on top of his cage and looks for me and thenviciously rushes in to bite my feet right through the shoes. He does this when I am sitting, standing or walking. If he is on his hanging perch, he falls to the ground and goes looking for me. We are truly baffled and I have bloody toes. Has anyone had this happen? He also attacks the dogs' feet. He does not go after guest's or my husband's feet. But will bite my husband if my husband tries to pet him when guests are around. We pass around band aids like candy! What is going on??
