Abandoned by his bossy wife and children, old Mr Ape finds himself living all alone in his huge and rambling house. And then he gets a brilliant idea: he can fill the house with animals the pets his wife and children would never let him have. But pets have a habit of increasing and increasing and soon every room is stuffed to the brim with animals. Something has to change . . .
