Heh, figured it would spark your interest ;)
I honestly can't find any other name than Maxximum (I spelled it wrong the first time). It specifically says that there are no Animal By products, No artificial colors, flavors or preservatives. As well as no corn.
I went ahead and took a few pictures of the bag to see if that helps at all. I've never heard of it prior to seeing it at Walmart, but a friend of mine who lives in Wisconsin has heard of it (I'm in California).
Heres what the bag looks like
