Hi, I have 4, 2 week old kittens, and the mother left me with her kittens in a box, I used my pointing finger to rub their heads gently then the eldest started hissing at me, and so did the other three. Then they started banging their paws at me. Why are they doing that? Did I do something wrong? Or is this just a part of their development? And at what age am I allowed to fully hold the kittens so they'll get used to me. A million thanks!
