Other Species
Although Brian Jacques says that he only uses British creatures in his books, he has plenty of non-British fans who roleplay or write fanfics about non-British creatures. Here is information on the species I know of that people roleplay. If you know of a species not listed here that some people roleplay or write fanfics about, then please tell me. There's no "In Redwall" section on any of these because none of these (with the exception of a brief mentioning of wolves in one book) are in Redwall.
