I dunno, I had two male Siamese that definitely followed that rule, but then we had a void and a mini Siamese, both girls… they mostly ignored each other. The void was destructive during her teenage years, but the Siamese was the sweetest cat I ever shared a house with. Both were smart.

Not a big fan of wrapping myself in bog roll, terfs or pumpkins, so its either magic or ghosts. Magic it is then!
