I think other mammals do have a cycle.... a swift google suggests that horses have a 21 day cycle during the breeding season, bitches have a 120 day cycle, cats will go on and off heat at length about 2-4 times per year unless bred/spayed.
I've a residual idea from somewhere that female guinea pigs will ovulate when near males, but I've no back up for that.

Certainly, it was my recollection that some animals only ovulate when they mate (i.e. they are effectively always on heat, but don't have any wasted cycles).

Why do I keep thinking about rabbits, whether it be about teeth or ovulation?

The rabbit does not show regular estrus cycles: that is, recurring periods of sexual desire. Ovulation in the female rabbit is induced by mating and occurs approximately 10 hours after the female is bred.

I believe large cats come on heat when a new male enters the pride, and kills all the current juveniles.
