Little Fox Escape

We often hear that people keep cats and dogs as their pets but you have a little fox as your pet. You had found this fox in the woods last summer. It was injured when you had found it. You took it to the veterinary hospital, got it treated by the veterinarian and ever since then the fox has been staying with you. One day you decide to go and spend some time in the peacefulness of the ancient and isolated house in the outskirts of the village. As soon as you got there the little fox that had gone with you jumped out of your arms and ran away. All the exits are locked and that means the little fox is surely somewhere inside the house. You must find it before finding the exit to go back home.
