Funny, for all these comments decrying snapping pictures of the interior of a residence, there have been a great number of threads such as
this one which advised doing just that (including some participants in this discussion).
The pictures are sufficiently anonymous to keep the owner from being identified, that's good enough for me.
I've known perfectly sane people that live in filth, particularly animal feces. It just doesn't bother them enough to do something about it. In fact, right now I'm trying to determine if I should continue my "Febreeze-can of fury" technique or buy new flooring to get my house sold, since a prior resident allowed cats to urinate all over the livingroom and the cat's bedroom with immunity. With the swamp cooler running now in the summer, those old odors are getting revitalized and harder to mask.
That prior resident would often throw a paper towel over vomit or feces in the house, with the intention of getting to them after they had dried. She was, to my reckoning, perfectly sane and capable of cleaning the mess. Her current residence also boasts the odor of her beloved critters.
I'd do the job shown in the OP, but I'd sure be complaining to you guys about having to do it, same as Phil.
I do think it is a violation of privacy to call the cops if someone is living in their animal's filth. I treat it as none of my business. If a human is tied and gagged in the basement with their feet soaking in a bucket of gasoline, then of course I would get involved. A lady who's too lazy to pick up or let out their animals is below my radar, IMO. That's where
I draw the line.
