Mama cat swatted my sister a few days ago for standing and looking at her kittens and my sister actually bled from her scratches. I initially brushed it off thinking maybe my sister have antagonised her in a different approach but today as I was just looking at her kittens, she actually bit me and scratched me while I tried to moved away. It came to me as a surprised as I was feeding her treats a few moments ago and lightly patting her and she suddenly went into attack mode. Now I am really scared of being scratched as she hasn’t had her nails cut since she was brought home. Feliway has already been installed in the room with her kittens..how do I calm her down? I do need to feed her and weigh her kittens everyday..
