Stray cats rarely have the desire to follow anyone about. That is just what is peculiar about them, just do your own part by leaving them food when you can.
I didn't know about this until recently and there's nothing you can do to force them home with you. They have mastered the street, also ready to live by it and make their own living. I will always keep food when necessary.
I contact animal care, they will come for stray domestic animals like that. That said, I never said I don't feed them. Once I see they come too often, I hand them over to people who can care for them better.
You are doing a good job by calling the animal care, I will also do same too. Animal care can take more proper care of them than what you are going to do.
They are already in the street and believed that they can fed for themselves. It has been a behaviour that they have mastered so well so I am not interested to keep one again.
