Is the maneki-neko a male or female cat?

Can anyone tell me, with certainty, if the maneki-neko, the traditional Japanese beckoning cat, is depicted as a male or female feline? It's a fascinating topic, as the cat's gesture of beckoning with its paw is believed to bring good luck and prosperity to businesses. But does the gender of this charming feline hold any significance in its symbolism, or is it simply a matter of artistic interpretation? I'd love to hear your thoughts on this intriguing question.
