We live in a country in which wandering cats are a lot and nothing can be done with the matter. It’s about 2 weeks that a cat come near our door and discharges (sorry) and goes. I hate cats and let it be their discharged matter!! How can I get rid of this animal?? I even don’t dare touching it. please help me. Is there any substance that cats hate much which I may put near the door so it doesnt come?
