Most of my ferals were the very wild, rip your face off if given a chance, type of ferals. They were all around a year old give or take a few months or so when they were trapped. Are all of them friendly, cuddly, lap cats? Not even! But they can be touched by me at the time and place of their chooseing and wouldn't leave my house even when someone left the gate open. The oldest ones are now 11 years old and I love all of them very much, even the ones I can't cuddle. But if they had been trapped and taken to any shelter they would all have been killed as too wild and aggressive. As long as you can live with the knowledge that the feral may never be a cuddle cat and may not even let you pet it much, you can live peacefully and comfortably with a feral or ferals in the house. Some of my ferals will sit a foot from me and do the slow eye close with me but most of the time won't let me touch them. OK, I can live with that.
