Years ago, my then-boyfriend, later ex-husband rented me a townhouse. I had a black cat that I let outside to pee. One day he came home with a slash on his thigh. The vet said it looked like a knife cut. We had a tall, scary neighbor who lived next door. Once we heard screams and a woman crying. We called police but didn't follow up since my bf was into shady stuff and didn't want to get involved. A year later, the neighbor moved. My ex went into his townhouse right after scary neighbor left because he was thinking about buying it. One bedroom had an altar and bloodstains, and other markers that indicated the neighbor was into the darker aspects of Santeria. Santeria is very common where I live, they sacrifice animals, I don't agree with that but that's their religion. But I know in my heart that asshole cut my cat for his blood for some kind of ritual. I still have black cats but I never let them outside. I respect Santeria and know most santeros and followers aren't evil or dark.
