If my cats just purred it wouldn't bother me at all. Sunny meows very loudly in my ear or he'll howl in the hall way and try to wake everyone up. Pearl will also go in my bathroom and start howling and then it echoes. Ziggy loves food so much that she'll start purring very loudly before I feed her. Starr used to do the same thing and he'd continue to purr while he ate. I sure do miss this.
