As I have said before, I have a lot of feral/semi feral cats around the farm. Most of the toms have grown up together, so get on ok ....although there is a boss amongst them!! None of the males are neutured.
One point I must make, is that, leaving a tom unneutured, there is the risk of him going off after females, and not returning home. Three of mine left home - but on the other hand, I have a ginger tom and also a black and whte one, who seem to have taken up residence at our farm. But, the other toms do not seem to wonder at all - not sure why!!
Most cat owners have their tom neutured at a few months old, and they must cope with the other tom cats?
Once they sort out whose boss, they usually all get on ok.
Entire toms do spray their territory, and the smell is not nice, and they also come back with ears in tatters, and scratched faces. So neuturing does stop these things from happening!!
