She's about two months old, and we adopted her from a cat rescue. No Fear would also be good for her; or Red, as she has the personality of a Red!
Missy (for Miss Chievous) is an orange female who takes control wherever she is, even up against our five year old greys. Within 30 minutes, she had explored about every bit of our place, upstairs and down.
Fortunately, she also doesn't mind being closed up in her room, which we do at night and when we go out during the day. That's the only way, one, the others get some peace; and two, we know exactly what she is eating and doing in her litter box. Also keeps the older ones out of the kitten food. The neat thing is, you call her and she'll run right to you in her room -- and we've only had her for four days!
