Chill... It's not the end of the world, and you shouldn't try bumping your thread if no one answered. It's either they don't know if Pet Stories can support CC or they don't play Pet Stories.
I do have Pet Stories, and yes, they can support CC. You have to find mods for Sims 2: Pets that will work with Pet Stories.
Also, there is another thread at Simbology
here where we discussed the game engines the Stories series (Castaways, Pets and Life) were based on, and which type of mods (Uni, NL, OFB, Pets and etc.) would work with these game engines.
In short, yes, Pet Stories can support CC. Use common sense when you decide what you want to install.
