Seeking advice regarding a kitty

[Demoiselle]

36. Actually, I think I would.

I'm a bit fanatical about it ever since a handsome grey feral tom cat set up his harem under our front porch.
I captured, spayed and released all the breeding females, found homes for all the kittens ( roughly twenty in all) except the five who are still, years later, in my house. They're all utterly tame, neutered and are never allowed out of the house anyway. And I love them all.
I have no idea what happened to their feral parents. I could never even trap the tom, so he wandered off when the action stopped to make trouble elsewhere.
There are so many feral cats struggling to stay alive around here....the thought of anyone allowing a tame UN-neutered "pet" to wander loose makes me very upset. Yeah, I probably would neuter him...it would be better for him than being hit by a car.
I'm sorry...I don't mean to harangue you.
Of course you should do what you can to find the owner.
