How often to feed ferals so they are healthy but 'behave' outside my office?

First of all excuses if this topic has been covered and if there is a link it would be appreciated:

In my office there is a floating colony of about 4-5 ferals. I personally arranged to have them TnR'd so they're fine on that end. Our office is in a heavily greened area so the consensus by our janitor is that they can hunt mice and whatnot. However I started giving them some kibble in the evenings, about a cup per cat, and one pouch of moist food at the end of the day. Every morning the pan is shiny clean, no a drop is left.

The issue is that lately 2 of them are now basically hanging out right outside of our office back door, which leads to the green area. They have even started to scratch at the glass and call out as soon as they see me coming form the hallway inside. It was cute in the beginning but now there are 3-4 cats outside the office door, the 2 at the door scratching, and the others about 5 feet away, just staring at me.

I'm worried that somebody's gonna get upset and want to get rid of them. In the old days they were really scared of humans and kept to themselves, only coming out when the food appeared. Now when they all stare I can almost sense them thinking "dude, it's 5 o'clock, what does one have to do to get fed around here". They act really friendly when there's food involved but as soon as I even think of bending down to touch them, they jump and run away.

Is there a way to scale back the amount of food or something so they stop ganging up on me?

Thanks!

If you feed them they will come (that's a version of a line from a really famous movie about baseball).
So, not really. If you put out food they will keep coming. You might try putting food further away from the office, at the edge of the green area.
Where do you live: I ask because if it is cold and getting colder, there is generally less food available--mice, squirrels, chipmunks while they don't hibernate don't come out from their hiding places as frequently. AND feral/stray cats need extra weight/fat storage to protect them against the cold. They need all the calories they can get. So that may be another reason they have incresed their demands for food.

Thanks! Actually I'm in Panama, so no cold here, just a lot of rain this time of year. My ID photo is of my main customer, he was laying on his back right outside the door and had just seen me.

I will try to move the food farther away. Thing is they know where 'the guy with the food' comes out from. They in fact ignore all the other people that use that door.

Unless I stop using that particular door so they stop identifying it with me. I can go out the other side and walk around the building and try to stay out of their sight for some days.
