That's not a hermaphrodite.You know, in the 90s I had a childhood cat that was a hermaphrodite. When they were given to me they were visually a female, we named her Purrl. Then later "her" testicles descended and visually they were mixed! Purrl acted like a fixed male cat, never sprayed or went into heat. Unfortunately they got distemper and had to be put down.
He was a male cat who, depending on his age, had either normal or delayed testicular descent.
Not all male cats spray, or may do only outside the home where you don't see them do it.
Sorry to hear he got distemper.
