Two of my ferals survived our winters, and likely several of the others..but yah, only the toughest ones survive, there have been, oh, half a dozen I never saw again.
Little Boy, the 'real' feral, 'we' followed for more than 2 winters, both of which hit -20F on several occasions.
He dodged dogs, coyotes (I've seen on my street!), foxes (in my yard), and eagles (a nest about 1/2 mile down the road), and endless hawks, etc.
I 'found' a group of about 8 'watcher/helpers/feeders' on NextDoor, who helped track his appearances and leave food out for him. We were able to plot his movements, and saw he commonly traveled about a mile, tho in winter he'd cut that in half by crossing the frozen lake to the houses on the other side.
I finally became convinced he was either staying in (the recently upgraded) storm sewers, or (this is the one I prefer) cuddled up with the opossum who had a den under my deck. (He gets riled over any critter he sees outside,
except possums.)
Eventually - after battles with other ferals and getting some pretty bad wounds, I got some help and trapped him. At first he was terrified - first time I tricked him inside, he ran right into a wall corner: He didn't have any idea about 'rooms' or 'windows'!!
But after his vet visit, he started purring and curling up with me right away! He hasn't shown any real desire to go back out there. I think of him as 'Monster Slayer'.
Oh, and later on, I had my vet investigate an odd lump in his side: She extracted an encrusted bb from his side.
Turns out he's a real cuddler - in fact drives the other cats nuts with his continual attempts to cuddle!
He also has a very distinct "Lion" walk/stalk - he kind of struts, just like an actual Lion stalking prey.
Ollie, who appeared here a year ago spring, had been spotted in November by another neighbor, so he'd been through at least one winter.
Discovering himself in the window.
I had assumed he was a stray, but his fur and coloration sure looks a LOT like the new Mom and Kittens, so I have to wonder if She is His Mom!
He sure races around the place like crazy any time he sees them out there!
Currently trying to figure out the best way capture all four kittens, and Mom, if possible...before winter gets here!
