I'm pretty sure I've said this before but anyway..... Maybe she's just doing a "Willie" imitation.
I have a pet male Parakeet named Bobie. He is let out of his house for exercise when I am home. At night, when I am watching the taped DS episodes of the day, he sometimes perches on my shoulder and watches with me. It appears Bobie especially likes the character Angelique. He could be in another room and once he hears her voice or laugh, Bobie knows it is time for DARK SHADOWS. Does anyone have a pet that watches DS?
