Welcome to InkscapeForum!
I'm not sure that exactly has a name, but you did a very good job of explaining (by providing verbal description along with image)! I'd say that different artists probably approach that situation in different ways, and whatever they find suits their needs (goals) and personal preferences. In that specific example, you'll probably have a few elements stacked on top of each other. (Well, many elements for a whole cat

)
For example, you might want to have 1 entire closed path, without the lines that you describe as curling up into the object, perhaps colored gold. And also, perhaps without any strokes at all. This would be like a base on which you'll build the rest of the features. You might have some white sort of crescent shaped objects to create the white part of the toes. Spots on top of the gold base. And then on top of everything, finally the stroked paths that form the outlines, including the parts that a curl into the object. Since your color is contained in the separate base, it won't matter that the top paths aren't closed. The top paths will probably end up being many subpaths of a single compound path, unless some of them will be different colors. In that case, you might end up with more than 1 compound path.
Let's see if I can make up a quick illustration.....be back shortly
