Does air-freshener cover up decomp in an aging Honda station wagon?

I can't even...  This is a blog that should not be written, but it is going to happen anyway.  I did purposefully wait until a little closer to Halloween to share this.

So- my hoarding mother's neighbor (the one that I talk to, and stopped by to visit last month) was on vacation with her boyfriend, and had left her precious little dog with a trusted pet sitter.  Her pup was a teacup poodle, was 13 or 14 years old with a pretty significant heart condition, but seemed to be doing well.  Long, sad story made short... The pet sitter threw the dog a piece of cheese, and the dog either had a heart attack at that instant, or asphyxiated on the cheese.  It was horrible.  The neighbor was on her way back from out of state when she got the call, and she had the sitter drop her dog off on her porch, in a box.  

Now, she was not thinking clearly, as it was 90 degrees or hotter that day.  (They had just had a cold snap when she left the state, and I do not think she realized that there was unseasonably hot and humid weather afoot).  At some point she called my mother to just make sure the dog was on the porch.  My mother drove over to her house, and picked up the dog until the neighbor got home, especially with all the roaming animals and vermin in the neighborhood.  My mother mentioned this in passing, but was more preoccupied with wanting to be macabre, morbid and bash the neighbor, the sitter, etc. and knowing that I would not be party to any of that.  I did not ask details, and changed the subject quickly.  Little did I know...

The next day she calls.  "Does that Febreeze stuff for cars work?"  Um... WHY?  "Why?  Do you not realize what happened here yesterday and I what I did?"  Oh my GOD.  She got the box with the dead dog that had been out in the heat, stowed it in her car, and parked in in her garage to... percolate for several hours in a garage that was hot.  She keeps her car closed up as well.  I was dry retching on the phone.  Decomp.  Her car smells like decomposition.  She has dead dog decomp going on in her car.  She acknowledged that since she has little to no sense of smell, the odor must be bad.  When I started asking questions, she started getting defensive and evasive, and ended that call as soon as she could, after changing the subject to tell me something about her feet that would make the most hardened person vomit.  

Add this to the list of horrendous odors that emanate from her house, her car, her person.

Dead dog.  Decomp.  I will never set a toe in that car again.  EVER.  

Hoarding.  No one wins.  No one.
