Our expert says:
Neutering is number one priority! Cats mark their territory by spraying urine and he is obviously doing this. Do other cats come into your home as well? Provide numerous litter boxes so that he has no excuse not to use one. Smakking the cat has no effect as you have found out. It's the hormones! So book him in for neutering. Your vet will be able to advise you about what to use until the hormone levels have dropped off (usually takes about 6 weeks). Unfortunately some cats develop bad habits that are difficult to break.
