sad story with a (hopefully) happy ending

[JessiSatts]

I had a cat and a dog when my parents divorced. Both animals lived mainly inside with us. When my dad re-married, my stepmom kicked both animals outside. Well, my dog didn't survive it for very long and when we had her put to sleep, she was in a horrible condition. The cat is a mancoon and is supposed to be fluffy and stuff. She's lost alot of fur and has gotten really skinny. I feel so bad for the cat. Keep in mind that she is about 8 yrs old and she's been outside for about 3 yrs now. Recently, I decided to move to my mother's house for the summer. I want to take Fluffy with me so she can spend her last few years nicely instead of like Niki (the dog), miserable.
I need to know what I need to do. She hasnt had vaccinations for a long time, I can't even remember the last time she went to the vet. She used to be litter trained. Is it still possible for her to be litter trained again even though she's been outside for a considerable amount of time and is an older cat? Also, my mother has two dogs and two cats already. I plan to keep Fluffy mainly with my in my room, but some interaction with the other animals isn't going to be avoidable. I would greatly appreciate any tips or information that anyone has for me. Thank you very much.

first thing...vet check up then the rest of the problems you will be able to solve with time and patience.. cats are stubborn but they will learn new things like environmental changes, litter box changes etc with time, it does take time though and patience....don't quite on her
