Hi, yes this would be explained by the fact that Goldu has not been neutered. He probably reached sexual maturity when he was around 5 1/2 - 6 months old and since then he is busy patrolling his territory, hunting and finding female cats. Things should improve by getting him neutered. This will obviously decrease his desire to roam and reduce the chances he gets hurt, involved in cat fights or road traffic accidents. Hope this helps !
