It's explained in Monroe's book that he read. To paraphrase, woged Reinigen are genetically similar, so they are able to "fuse" together when in groups. Their woged state also activates the growth of certain cells in their body that are "cancer-like." Once the Reinigen start merging together, their genetic similarity causes one Reinigen to become part of the greater whole, the Riesen-Ratte, essentially one giant, mutant Reinigen.
