Help! Does anyone know why my male neutered cat ( The Lion King) is starting to spray urine in my house? He was  a stray so I have no idea how old he is. He's a great cat,  very gentle and lovable so  last summer I decided to keep him and got him neutered. It stopped him from fighting the neighbor's cat and calmed him down and I let him come inside now and then to visit. He stays outside most of the time as he is not litter box trained and also wants to claw the couch.  He has been fine until a couple of weeks ago -  now he'll come in and want to spray on the furniture! I thought neutering stopped that behavior but read that unless the male cat is under six months old when you get them neutered they still will spray.  So what do I do to stop it? I want to continue to let the Lion King come in now and then but if this continues I won't be able to!  I also have two indoor female cats and one indoor/outdoor female cat, all spayed.
