It seems that this friendly little cat may be a stray, although the amputation of his front leg looks surgical rather than an accident.
If any one is having problems with him spraying around their doors, gates etc wipe away any surplus urine with paper towel and then wash/flush the area liberally with a solution of biological washing liquid/powder and warm water - about a 10% solution so 10ml to 1litre of water will do the trick. Use paper towel or disposable cloths. Rinse and allow to dry. You may need to repeat the process if there is still a residual smell. Finish with a light wipe over or spray of surgical spirit.
Take care on all delicate or painted surfaces - test a small area first.
No, no sign of an owner. He is in pretty good condition for a stray so although he's not neutered I am surprised that he doesn't have a home in the village.
