They provide the most comprehensive magical protection against occult powers and curses. These cats are most adept at nullifying powerful negative energy that may be dwelling inside a home.
Interesting. I don't believe that spirits are real, but this was interesting to read nonetheless. I received a new pet -- a black cat -- when I was 12 years old. Incidentally, something "odd" was going on in the house that I lived in at the time, to the point that my parents had to bring in a priest to bless the house. Maybe that cat came into my life as a protector of sorts. I suspect that whoever lived in that house before us probably engaged in some type of occult practice, and maybe there was negative energy leftover from those previous residents.
