At one time I was told it is impossible to "tame" any feral cat unless you caught them before they were 8 weeks old, but this is not true!
I live in the country, on 10 acres, with no neighbors in sight. An old house sits as it waits to fall in on itself, and from time to time a feral cat had litters in the house. Although we tried to trap her we were never able to but we currently have four of her kittens (from 2 or 3 different litters) in our care, only one of which was caught as a wee kitten.
We know these kittens had been living wild their whole lives, and yet now all are tame, and you would not know they had been without human contact for much of their early lives. The latest was well over a year old before we managed to catch him.
How to Tame Young Kittens
To tame young kittens we would keep them in a small cage, as for guinea pigs, but a dog kennel would work too, or even a very small bathroom (keep the toilet lid shut). The kittens need dry food, water, and a small litter box. The idea of the small cage makes them easier to catch.
As many times a day as possible (at least 3 times) you should go in and hold each kitten. They will hiss and freak out so you must be unafraid. If you are worried about the kitten getting away from you, do this in a room with the door shut at first. Hold the kitten for at least 15 minutes at a time. Eventually there will be a time when the kitten will relax and even start to purr.

When you put the kittens back in their cage then offer them some canned food on a plate. This way they associate people with good things. Eventually the kittens will be less afraid, and will even start to climb up the cage to get attention/food. The overall taming process can take 1 week or more depending on how old and how feral the kittens are.
