Three houses stand in a row, numbered 1 (left), 2 (middle) and 3 (right). Each house has a different color (red, green, blue), a different owner (Ana, Ben, Cleo) and a different pet (cat, dog, fish).

1. The cat lives in the right house.
2. Cleo does not own the fish.
3. The owner of the fish lives in the blue house.
4. Ben does not live next door to Cleo.
5. The green house is immediately to the left of the red house.
