Many years ago, we had a cat who was an outdoor cat. She "adopted" us and as hard as we tried to keep her indoors, it wasn't going to work.
One Halloween, she came home covered in kerosene. Apparently, someone on "Mischief Night" tried to set her on fire. She managed to get away (probably bit the hell out of whoever had her).
However, when she tried to clean herself, she injested the kerosene. We rushed her to the vet, and they managed to clean her and medicate her to counteract whatever she swallowed.
Thankfully, she survived the ordeal.
