just about at wits end. Some cat comes around once a week and sprays the front door and then the smell goes through the house. Deodorizer and white vinegar wont get rid of the smell.  To try and disuade the cat over last year  I have sprayed the area with white vinegar and planted a couple of lavender plants each side of front door to no avail.   I have sprinkled cayenne pepper also to no avail.  Orange peels and lemon peels and citronella spray also dont work.  So went to mitre10 and got STOP Cat and dog repellent and every 2 days sprinkle the green smelly crystals around. Also doesnt bother the cat.
 Anyone have any other ideas.  Normally I dont mind cats but this one would defintely benefit from lead pellet if not in town.  I think I know which the culprit is as I keep chasing a ginger tom away when I catch it spraying around the hedges.
