But recently, Sandy’s behavior began to change. Every night, she would walk into the child’s room, sit beside the girl, and start… hissing. At first, it was quiet and almost inaudible. Then it grew louder, more intense.

At first, the parents didn’t think much of it — they blamed it on the cat’s quirks, her age, maybe some dreams. But the hissing happened again and again, always near the child’s bed, and only at night.
