You’re wrong. My experience with one says differently. Once they’ve weaned off momma, they’ve already been habituated to being feral. Pushy, insistent - only thing they’re after is food and will trash up anything to get at it.
I don’t know what accounts for your one experience but it isn’t what other people experience, some even make fully adult ferals inside cats, I think the adult feral that lives in his pet house in my tiny enclosed front porch with 2 strays, both with their own houses, could be brought inside easily if I chose to but I prefer them living around the front door.
If you are talking about damaging furniture, that is a possibility that any cat owner has to face in training.
I adopted my beloved kitty Zizu from an adoption center when she was 7 months old and recently taken off the street. At first she was a bit shy, but you couldn’t shove a piece of paper between us now, 9 years later. She’s always within a few feet of me, if not on my lap. Purr, purr.
I don’t know whether a feral animal can become a house pet, but house pets start behaving like feral animals when abandoned. My hometown had a problem with packs of dogs that would attack smaller dogs and people. Now and then, the police had to pull up and shoot the larger dogs. The local paper investigated and found that people in the wealthier surrounding towns had been dumping their dogs in our town. Some were caught pulling up in their cars, pushing their dogs out, and driving away. Coincidentally, back then, the Republican party ruled our town. I don’t think the dog-dumping was political, though. I think people in the wealthier towns just looked down on our working-class town, and they didn’t care about their pets, either.
