I'm also going to teach them not to play with headphone cords.
As for violence and attacks, I haven't seen that with the 20+ I've had over time. Some will try to wrestle with you (look at what they do to each other) but they can be taught that humans are not toys. Mai Tai wrapped up around my arm (gently) a couple times. A stern NO and taking her to a toy got the point across. She's been nothing less than loving to everyone. Yes, cats can be trained. Not obediance, like dogs, but they absorb rules and limits pretty well.
It also helps to socialize them young. These absolutely will be. They'll be picked up, held, turned over for bellyrubs, tails touched often, and so on. They will start associating that with affection and come to enjoy it. They need to be handled a lot and loved. Do it to them early and they'll see humans as a source of attention and love while being playful with toys and other cats.
Cats aren't aloof, either, if you treat them right. They're solitary predators hardwired to be inconspicuous, so they pretend not to care. Mai Tai appears not to care, but never lets me out of her sight. She keeps tabs on me if I go into another room. My cousins' cat "secretly" stalks them when the walk the dog. She hides behind stuff and sneaks around, but won't let them get ten feet ahead of her.
Holding an animal for a few hours is great, too. I love having a cat draped over my lap while I listen to music or watch a movie. Cats sleep up to about 18 hours a day and love to cuddle up while they snooze.
At any rate, I'll do my best with these kittens and try to perform the desireable lapcat mod. Pretty good chance since the mom is gentle and friendly. Not sure about the father, but it's probably the long-haired black and white tom in the neighborhood. Nice guy, he throws himself down at my feet and cries until I rub his belly. Nice guy. They have potential.
I'll get pics up when I can and I'm sure they'll get homes. My cousins are interested in one. I might take another. And we have tons of family friends, so they'll all end up spoiled housecats. I'd be happy to pass one on to a Head-Fi'er, too. You're all friends.
