Someone has already offered to pay for the vet to have it euthanized - she rejected that option.
Instead, she has decided to delete all of her posts and act like everyone in the world but her is Just Stupid.
I wrote to her local animal control claiming that I had some concerns about a neglected animal, offering to send photos, their IP address (we've confirmed that she and Mr_Pat live together) as well as the name of their ISP and the name of the town they live in. It will take a court order to get more information than that, i think
We'll see what the AC says. I'm feeling pretty defeated.
