When a male shows sexual interest (often called "mounting" or "humping") in a spayed (fixed) female, it is usually more about than actual reproduction. Why It Happens
Spaying removes the ovaries and uterus, eliminating the heat cycle (estrus) and the pheromones that attract intact males. Can "Attraction" Still Occur?
