If they are really ready to condemn the place, and you are worried about biohazards, she should be more concerned about having a new place to live, it doesn't sound like cleaning this place is worth it. Is she older? We had a dog hoarding situation in Michigan last year, I think they put the person in a group home after hospitalization for mental evaluation. That was an actual house and they demolished it. Cities now have departments working with senior citizens on this issue as it is becoming common. It sounds like she hasn't really told you the whole story and is maybe making a last-ditch effort? Or are you taking too much responsibility upon yourself because you see she is not? If so, yes, you have our "permission" to back off. As should I!
