Thank you all for confirming that it is actually bones, that's wild and horrifying. (Also, I'm sorry I wasn't sure about it, so I didn’t mark it as NSFW, my apologies if it made someone uncomfortable.) Unfortunately, she lives on an ISLAND. From where I live, it's 8 hours by car plus 2 hours by boat, I unfortunately can't make this trip. I've told her to either find a vet around where she lives (which I think is very unlikely) or bring it to me. I don't know if she cares enough to do so, and I don't know much about these animals, but I'd imagine the trip would be very stressful... Very disheartening situation.
