I have a 14 inch female leopard, and two 7 inch males. The males are eager to mate her, but they're having trouble getting the job done due the size difference - I'd like to hear from anyone who's had mating pairs of very different sizes about whether this failure to mate is likely due to 1) purely a bad anatomical fit, or 2) that my female may not be cooperating. Am considering finding a larger male, or else just being very patient....
