Please bear with me as I display some autism.
Liking ferals isn't a fetish, it's technically a paraphilia. Liking anthros is a paraphilia too, for that matter.
You might search for that and get some nasty words on the matter because usually "paraphilia" is used pejoratively, so let me just clear things up.>Paraphilia>Any intense and persistent sexual interest other than sexual interest in genital stimulation or preparatory fondling with phenotypically normal, physiologically mature, consenting human partners.
In recent years, a distinction has been made between paraphilic inclinations which are not harmful, and ones which are. Individuals who are in control of their paraphilia, or have a paraphilia which is not harmful to themselves or others, are no longer considered to have a paraphilic disorder. These kinds of paraphilias are instead pushed towards being "sexual orientations". If anthros and intelligent ferals were real, then wanting to date, marry and bone them would be sexual orientations in a sane culture. Since they can't into real, liking them in a consistent and sexual way is a paraphilia.
