I adopted my kitten about a a month ago, she is 3 months old. She is rambuntious and crazy ALL the time. If i'm trying to study she will jump on me and knock everything over. She knocks lamps over and bites and scratches all the time also. She has bitten through 2 different headphone set wires and my dvd player wire as well. I know she is young and just wants attention but its out of control and i dont know what to do. When she does something wrong i tap her on the head and say "NO" very loudly but she doesnt seem to learn anything.I dont know what to do, i just want a normal kitten, help!
