My elderly neighbor is a packrat and thankfully not an animal collector. She has three rescued cats that are spayed and neutered. Her kids "help" her clean when she is in the hospital. She can't have less than two of anything I swear it. She has stuff up to the ceilings in her rooms. I know what I would do if she were an animal hoarder. I'd sneak off as many female animals as I could without her noticing. I'd guess most of them are feral and not used to handeling so she'd not notice some being gone.
