So, the people suggesting going to the shelter…you’re not having a kitten shortage in your area too, then? The last of my mother’s elderly cats died recently, and no one has kittens. Not the NHSPCA, not people giving them away in the paper/freecycle/craigslist, not through the area vets (one vet took her name saying she was the 20th person to ask), only one person in the area is even selling them- not that she wants a $450 kitten, but she might have found a private rescue league that has some. She’ll find out tomorrow.
Anyway, regarding feral kittens: ten years ago a feral cat had kittens in our garage. We managed to catch one kitten when he was about eight weeks old, and gave him to my aunt Gerry, who’d recently lost her 18-year-old cat. Then the following week we tried to catch the other two without much luck. A possum attacked the remaining two kittens, killing one, and badly injuring the other that the mother then abandoned. We caught that one and it hid in the pool table for three days.
Sam, my aunt’s cat, has happily been a house cat for a decade. He scares the crap out of many visitors, but he’s gentle with her and besides throwing her food on the floor - he won’t eat it, just bats it off the plate - she has no complaints.
Boo, on the other hand, was an indoor cat the five years we had her. She was pretty happy, but never a lap cat. The other female cat got very ill and managed to make her feel so unwelcome that she snuck out past my mother one Halloween night and didn’t come back (thank god she’s spayed). My mother thinks she’s seen her a couple of times since she took off, but if it was her, she is obviously feral again. I sort of think seeing her is wishful thinking, but it’s remotely possible since she had a distinctive orange stripe running down the center of her otherwise black face.
Basically it’s a crapshoot since even kittens from the same litter react differently to being brought into a home. I suspect if you make the cat your only, like Sam is, s/he will feel more secure, but who knows. If you go through with it, I wish you luck.
