I saw this short a long time ago,I cannot remember where or when ,but I have never forgotten it,which is pretty amazing since its running time is about 20 min.An old man lives in an old house ,surrounded by dozens of cats.He treats them like human beings ,feeds them with love and tenderness .They seem like a true family.One remarkable sequence shows the old man playing Wagner's " Tristan and Isolde" to his feline audience.He tells them the story.Then he takes some food and he comes down to his cellars.And then.... The ending packs a real wallop .I will not reveal it of course.Every time I remember "l'homme aux chats" it gives me the shivers.
