My method for getting cats to be more trusting:

Sit six feet away from the dish when you feed them. Do Not Move. Sit absolutely still. In a while, the cat will come to the dish. Allow it to feed without even wiggling a finger. Let it decide to leave on it's own. Talk softly while the cat eats.

The next time, sit a little closer. Try to move a finger slowly. If the cat doesn't bolt, try to move your whole hand, slowly and in small bits. If the cat does run off, continue talking but pull your hand and fingers back to your body. The cat should come back in a little while, especially if it's hungry.

Do not get up when the cat is feeding or is close. Wait for it to leave or at least be several feet away.

Repeat the feeding routine, getting closer every time. Eventually you should be able to put your hand near the cat's cheek while it eats. Then it's just a short reach to touch it.

Make all movements very slowly.

The cat may surprise you and walk right up to you after a couple of days. Or it could take several days to let you move at all.

I try to feed twice a day at the same time. Cats catch on to the schedule real quick!

Good luck.
