Hope someone out there can help me with this.Once a cat has sprayed its scent all over your backyard & then proceeded to use it as its own personal toilet what can be done to stop it.I dont want to buy a dog or a rifle(iv'e never seen the culprit anyway),& iv'e tried cat repellents from stores(but maybe not the right one).Jeyes fluid was one suggestion but the rain kept washing it away.Bottles of water another.It started off in the planters,threw them away,but now it just uses the floor.Sorry, not a pleasant topic,but any suggestions will be appreciated.
