Eureka!!!
Ok, for years I've been talking about this book that I read a review on in Cosmo and really wanted to read, and I think maybe I finally found it. Either I had the title wrong, or it's not the same book, but it's definitely the same subject matter. I thought it was called Anarchy of the Rat, which honestly is a better title than Team Rodent: How Disney Devours the World, but it's the same idea. Now to see if the library has it!
