"One suggestion was a "test" (like a pregnancy test) that could be purchased to determine the gender of the box before it is birthed. I don't know if this is possible, given the scripting of the cats. The gender may not be determined until the moment before the cat pops out the box, or it maybe determined as the box is created in the system. Either way, this is another alternative, and would bring income to KC's.

I wish they would update them to just show on the box and not another booster or expense, it would bring more happiness to breeding and buying and selling overall and greatly improve the product.
Really could use this before birthing though!
