Queens are what kind of ovulators?

Explanation:
The key idea is how ovulation occurs in cats. Queens are induced ovulators, meaning ovulation is triggered by mating rather than happening automatically on a schedule. When a queen mates, the stimulation initiates a hormonal cascade that leads to an LH surge and ovulation. This is combined with a seasonal pattern: the queen’s breeding typically occurs during a certain part of the year (spring to summer in many environments), so ovulation tends to align with that window. In warmer climates, breeding can be year-round, but the mechanism remains: ovulation is prompted by coitus, not spontaneously. So, the best description is that queens are seasonal, induced ovulators. They are not spontaneous ovulators (which would be triggered without mating) and not continuously ovulating year-round in the absence of mating.
