The kitten my aunt found has a permanent home

My aunt/uncle got her spayed, all her shots done and had a chip in her ear. The little girl is known as Missy. She is 5months and still very skinny. Still hasn't gain any weight since my aunt found her. Now they let her roam free in the living-room but she can't go upstairs all by hershelf because Kari is up there and she spends all her time in the spare bedroom. She hates other cats and she would fight with any female. Her younger cat Molly wants to be friends with her but Missy doesn't want to be bother with her at all. At least they don't get in fight with each other. Both of them can live in the same room together but they are apart from eachother. Molly is a very jealous girl, doesn't like it when the kitten gets all the attention. Now she spend all day outside and doesn't hang with her mommy and daddy since the kitten is downstairs now. Three females can't live together, it will never work out. I'm glad it is a happy ending. Has anyone found/rescue a kitty from the street and kept him or her? Please reply. Thanks!

yes, Cindy is from a rest area; Andrea was rescued from the side of the highway; now I'm in the process of adding Tommy-Scott, a stray who has tamed down very quickly.
maybe Molly needs to be the center of attention for awhile - that way she doesn't feel threatened by the kitten and in the end, they will all get along better. i know it's hard to resist kittens, but Molly does have "seniority".
Do you have any pictures to share? We love pics

We took a few pictures of her but having the picture developed!
