I finally found some useful information. Seems I needed to google male calico, instead of mi-ke, and bob tail. Very rare, but possible, with xxy, thus most likely sterile, which is fine for me and my imaginary cat purposes, might make him less likely to spray in Mik's house. Plus the mi-ke male rarity but still possiblity does add to the cat as being special and bringing special fortune with him. Which indeed he is, and does.
