In 2016 we realized we had a feral cat colony and the latest batch appeared that spring. So to prevent this from happening again, I found a place (SAVE Rescue) that let me use their cat traps to TNR (trap, neuter & return). I did this for about 11 cats.  But we kept a few of them. Our newest adoptee is the mother of most of them, she comes inside but is still hesitant to get close to people. I think she finally has a place to relax being in the wild for so long and popping out babies. We no longer have any kittens, just a few visitors that make their rounds.   ~ Micky
