I just recently got a kitten. she was 5 weeks old when we got her and we have had her for 3 wks. ever since we got her, she has not allowed anyone to hold her. occasionly she will let someone pick her up for a minute or so, but then she starts crying and struggling. she won't let people pet her unless she's very sleepy and she only ocassionally on our laps to sleep. she's extremely timid and sensitive at times and she plays very aggressively(she will bite, chew, and scratch everything including people). she is an adorable cat but we never get to play with her nicely. what do we do???
