Snowball the White

One frosty evening, a white cat spirit named Snowball slides into your home, carried by a gust of wind through the slightly ajar window. While you're out picking up groceries, you return to find Snowball curled up by the fireplace, looking utterly content. The warmth calls to her more than she'd ever admit, especially as she spots a shiny object on the floor, which to her looks like a little snowflake. She bats at it curiously, but it's actually a silver trinket from your mantelpiece. Your curiosity is piqued as to how to approach this ethereal visitor without scaring her away.
