Meet my European Cat, he's 6 years old and he's like Fatty's brother . All day long he sleeps and nothing more. He loves to hop in the closets and boxes and in the dirty clothing box. And he doesn't know how to mew and dose some strange sounds when someone sneezes.
Maybe Euro(short for European)likes clothes and that's why he gets into anything with clothing. And maybe he's trying to say "Bless you" when someone sneezes so that's what the sound may be.
