My elderly mother lives with me and my daughter. We recently got a kitten. I was told she was 9 weeks when I got her (I haven't had the chance to go to the vet yet) but I think she is younger, maybe 6 weeks. She can be so sweet but then she turns into a she devil!!!! She bites and scratches and takes off running. She particularly does it to my mother, and she's got thin skin and I worry about how she bleeds. One thing that is enticing, my mom uses oxygen 24/7 and its enticing when she has this cord dangling that the kitten can attack (in fact I have to monitor her carefully around it and keep her locked in her own bedroom at night when we are sleeping (my mom sleeps in the living room). So...my mom has tons of problems with the kitten and we've tried a water bottle, yelling and screaming NO! at her loudly and tapping her nose...everything we can think of to make her know its not right to terrorize grandma! Any suggestions? I am going to get her nails clipped tomorrow, which may help us, but still I want to curtail the agressive behavior before it gets out of control.
