What do people who live in neighborhoods do with the bodies of their dead pets??

[Kitty]

I went to a big box pet store about a month ago to pick up some fish food and there were two really cute black kittens for sale, but when I went back about a week later they were gone.

When I asked if they had been sold, the employee said No, they put them somewhere else for the month of October and won't let anyone buy black cats/kittens as it gets closer to Halloween because of people who use them/kill them in their satanic or superstitious rituals around Halloween.

I was pretty surprised and didn't realize people actually did that stuff.
