Why wouldnt you have him neutered?
If he isnt neutered he is at risk of all sorts of horrible diseases including feline aids, he will wander in search of females and fight with other male cats causing injuries and large vet bills and he is very likely to spray all reound your house. There are so many cats and kittens that are homeless because people dont spay and neuter their cats, so many healthy cats and kittens are having to be PTS - please have your little one neutered so that he can have a long and healthy life with you
