I have heard that you are not supposed to hold kittens until they are older but I have never believed that I have always held my kittens from the time they are a few minutes old, only about 2 or 3 seconds a day at first then a little longer each day, and I have had no problems with them, actualy they grow up to be very tame, the other day I brought one of my cats to the park on his leash and he was'nt even fazed by the little kids wanting to pet him, one of the parents even commented on how calm he was, what is your opinion, when should kittens be held.
