It is not Spanish but English, where furry means "furry", and is a colloquial way of calling the "cute and furry animals that generate tenderness", which in the cosplay environment also became a style for the costumes of characters such as anthropomorphic animals (and furry). From these is that it is used in Spanish as a paraphilia for those who are sexually stimulated with stuffed animals representing animals, or with partners disguised as animals. See philia, lagnia.
