Morning all - lovely day - off into the garden soon.
DD - certainly sounds as though 'something' has happened to make your cat nervous of going outside. I agree with some of the previous posters to keep him in at night with a litter tray and with the flap locked. I highly recommend using a Feliway diffuser close to the cat flap and where he sleeps. I would also clean the door and the cat flap with diluted biological washing powder solution then rinse off and spray the door and flap with Feliway in case another cat has been nosing around there. Hope you can buy Feliway in France!
When I helped run a cattery we sometimes had cats who were reluctant to use a litter tray. We found that a covering of soil from the garden sometimes helped encourage them.
If the problem persists a trip to the vets to make sure there is no underlying medical problem might be on the cards.
