My sister has Momma outdoors and after numerous litters of kittens, some of which are still in the backyard, some are in the house, and some in the house are grandchildren of Momma. We've found that each "feral" cat is different. Of the ones that came into the house as new born kittens and raised by their mother (in a big cage-because the mother needed care after giving birth) and my sister and have been handled from birth, some are friendly and loving, others tolerate humans and remain feral. Then there are the ones that came in as kittens (such as when Momma knew that they were sick and she brought them to my sister to care for), Ashley is friendly and loving. Then there's Smokey who grew up outdoors, coming in when he was 1 1/2 years old. Don't even try to put him back outdoors (like one time when he was naughty and wouldn't get along with one of his brothers), he'll be right back in as soon as he can. That taught him, and he's loving and friendly. And, they all came from the same ancestory. Then, a number of years ago, from a different ancestory, 2 of the 3 remaining kittens remained feral until they turned 10 years old and did a complete turn-around. (The first kitten was raised by my sister after her mother rejected her because of health issues, Tablett was such a nice cat her entire life, even with her health issues.) Each cat is different, with its own personality. Love them all for who and what they are.
