Unknown.
Viseral horror, due to its almost documentary like realness. An early scene shows the killers hideout, complete with disinterested cat. Surprisingly unlike most horror films, nothing bad happens to the cat.

Kitty.
Someone is murdering members of the MacGrieff family, all witnessed by a lazy cat, in this stylish but mediocre Giallo.
