1-Dude fetishing feral animals in general is zoophilic, not their parts, it's the same idea by being attracted to a human with cat ears and a tail
2-Dude they mean in non-human as in Feral, And if you know that you should know yiff isn't entirely sappose to be zoophilic, also anthros aren't "non-human" animals they literally have human traits, they specifically said zoophila is being attracted to "non-human" animals
3- Apples and oranges are similar though, and some anti furries are actually fascists, also wouldn't comparing yiff to feral porn be like comparing apples and oranges as well?
