Popis:	We show that the categories PsTop and Lim of pseudotopological spaces and limit spaces, respectively, admit cofibration category structures, and that PsTop admits a model category structure, giving several ways to simultaneously study the homotopy theory of classical topological spaces, combinatorial spaces such as graphs and matroids, and metric spaces endowed with a privileged scale, in addition to spaces of maps between them. In the process, we give a sufficient condition for a topological construct which contains compactly generated Hausdorff spaces as a subcategory to admit an $I$-category structure. We further show that, for a topological space $X\in C$, the homotopy groups of $X$ constructed in the cofibration category on PsTop are isomorphic to those constructed classically in Top$^*$. Comment: 26 pages, corrected typos, removed some well-known results from the preliminary Section 2
