My toe nails are getting much too long and sharp. When I perch on a hand, sometimes my nails penetrate the skin. Sophia tried to file my nails. She can only do one at the time, because for me it is a nice sporty game to grab the file with my beak and hurl it away as far as I can. Sophia moans and groans every time she has to go after it. Sometimes I think that she has no sense of humor.
