Re: New kitten!
Welcome, and you CAN turn this little kitten around with proper handling and socialization.
I have fostered and tamed numerous litters or kittens, orphaned litters and adult ferals. Here is how I would handle this kitten:
Place the kitten in a small room with only one hiding place that you have access to. I like to use a bathroom with food/water, a litterbox and a cat carrier. I place a fluffy towel in the carrier and drape another towel over the top of the carrier to make a 'safe cave' for the frightened kitten to hide.
After a few days, I would visit the kitten often, bringing good tasting food treats. I like to use cooked and shredded chicken mixed with a lightly diluted can of Cream of Chicken Soup so the chicken bits will stick to the end of my fingers. I would put my hand into the carrier...of course the kittens would cringe away and hiss...but I just held my hand still, about 6-10" away from them and eventually, they just can't resist the smell of the chicken and they would eat out of my hand.
Each visit/feeding I would try to 'lure' the kitten further out of the carrier and try to get it to come closer to me for the chicken. When I would bring canned food on a plate, I would pet the kittens. I don't dab hesitently at the kittens, I would just pet them like it is No Big Deal. I don't stare at the kittens. In cat-language, stares are aggressive. Instead, I would slowly blink my eyes at it, or catch its' gaze and then slide my eyes away, while humming "uumm-huuummmmm, um-hm-huummm" in a slow rhythm.
When the kitten is starting to come out to eat and allowing me to touch/pet it, I would then start to handle it to get it socialized. Use a towel over your lap, or wear sturdy jeans, and place the kitten on your lap when you sit on the floor. I sometimes have to lightly hold it by the scruff, and sometimes I only have to cradle it around its' chest, to hold it on my lap. Without staring at the kitten, I keep myself aware of how it is responding. The kitten may be scared and you need to be aware of this, but handling the kitten will show it there is nothing bad going to happen and they may eventually like the massaging feel of being petted and rubbed.
At first, I only handle the kitten for between 5-15 seconds. I firmly, but gently, rub the kittens head and shoulders around my hold of them. IF the kitten relaxes and appears to enjoy the handling, I will loosen my hold, ruffle the fur at their scruff to remove the memory of the 'hold' and pet them as long as they like, allowing them to leave my lap if they wish. I keep rubbing and handling them as long as they are within my reach. IF the kitten does NOT relax, I handle them for 5-15 seconds, keeping aware of their tolerance level, and then I would set the kitten away from me at the opening of their 'safe cave' and let the kitten go. I don't look at the kitten, I don't want it to see me looking at it directly, as that would re-inforce in their mind that I am a predator interested in them. My goal is to get the kittens/cats to leave me slowly, I don't want them to run away. I want to handle them and allow them to learn: I will handle them. I will not hurt them. I will not keep them still fovever. I will let them go. It is No Big Deal.
There is a member here who does not approve of my methods of the sort of "kitty boot camp of handling" that I do, but experts agree that handling and socializing kittens right away will help the kitten to progress and become a loving member of the household. Yes, you do need to be aware of the kitten, its' fear level, what its' limits for handling are and not push it over the edge of what it can handle...but you DO need to make progress with the kitten; constantly pushing it just a little bit further past the barriers it has put up, until eventually those barriers fall and the kitten believes it can trust you.
It is my belief that if you leave a cat/kitten to its' own devices and let IT choose how much handling it allows you to give it, there is the very real possibility that the kitten/cat will NOT progress on its' own and will not learn to become socialized because it is just fine with the status-quo and has no desire to proceed further. This is where I feel pushing the issue results in breaking down those aloof and distinct barriers and can help a cat learn to like/trust people and become an enjoyable household pet that is relaxed and confident around all people.
Best of luck,
