Rib padding and Fur Question

I'm going to be starting on a new suit pretty soon and I was wondering if you guys could help me with something.I'm making an extra toony stray cat. She's gonna be really thin and scraggly looking, with a balding and bandaged tail. She's also gonna have torn ears and bent whiskers, you know really mangy and scruffy looking lol I'm putting pics of her below the cut

Well I want to give her rib padding to make her look thinner but I can't seem to find any examples of rib padding on suits. Does anyone have any? if there even are any lol, I know scrawny and boney isn't really a popular choice for characters xD

Also, I'm thinking of using Mendels gray mountain goat fur for her main color, does anyone know of any suits where this fur's been used? I ordered a swatch but its tiny and I wanted to get a better idea for how it looks on a larger scale before I order it.

Here's some pics of the character so you get a better idea of what I'm going for(mix the colored reference with the sketch to get a better idea)
