When she opens her mouth & meows, there is no sound. But she can yeowl very loudly. She came to me, after living in closet for 3 years. The place she was in, had too many other critters & they made her nervous. She's never been nervous with me. Loves to be petted & scritched. Bit of a spacie thing, though. Has that 'lost my thought' thingie down pat.
