Kitty sleeps holding hands with Mother and myself. Last night she nipped Mother on the hand. Mother has a small mark where kitty either scratched or nipped her. I yelled and batted rolled up paper at kitty and also will make sure kitty has 3 x 15 minutes of daytime activity/grooming as recommended online. Mother is mad at kitty. I have moved kitty's food out of the bedroom and moved the litter box to my study from the master bathroom. The new rule is that kitty does not go in to Mom's room unless I am there and fully awake. My bed is right besides Mothers and it happened while I was sleeping right beside both of them. Mom just awoke from a nap and didn't like the door being closed or being separated from Kitty. There goes the new rule enforcement. What have others experienced. What got in to kitty? I have been keeping kitty inside so she does not bring any dirt or bugs in from the outside. I don't want to change that. kitty is an older cat and has a heart murmer. What have others experienced. Will kitty nip or scratch again? She was pretty upset after I batted paper and raised my voice at her. I have had cats before, kitty is among the sweetest and most loving. She is the only one who has had an aggressive act. She is up to date on all her shots. I did not like keeping Mother's door closed. Have others experienced similar incidences? I think we should keep Kitty out of the bedroom at night time. Mom will probably not like that.
