Hello, my 6 weeks old kitten is jumping and biting us and scratching us even if we are sleeping. I guess she doesn't know that it hurts.. we tried 'time out' , 'say no loudly' , make her busy with toys but unfortunately nothing works.. I put her outside of our bedroom and closed the door because she bit my husband's month and he was sleeping. He was mad at her.. I want her to sleep with us but before she sleeps she bites and scratches a lot. What should I do? Please help!
