Hmm this is just me, but so far it seems harder to find non-furryart comics here among the animal-themed ones, so I'm (hastily) assuming it's a similar situation with furry novels. Meaning you could attract a sizable audience here? 
If not, in additional to Tapas forums, this may help: https://forums.furaffinity.net/
I don't hang around there much cuz my team's comic isn't exactly furryart, so not sure how the community there is like.
Anyway, not too familiar with the novel world, but they do have tags like #furry or #animal right? Usually, as a reader, I tend to search through tags rather than genres for stuffs not obviously tied to popular genres. Hope that helps.
