On Sundays, I scrub down Bella's cage. Normally when I am home, she is either on top of her cage or on me. This past Sunday, she stayed in her cage and every time I tried to get her out, she tried to bite me. And when I finally got her out, I realized that she thought that if she stayed in her cage, I couldn't clean it. And wouldn't you know it, after I cleaned her cage, she was back to her normal self. Do your birds try to outsmart you?
