A rare calico is typically a male calico cat. This is because calico coloration is linked to the X chromosome, and since males have only one X chromosome, it is uncommon for them to exhibit the tri-color pattern that defines calicos. Genetic anomalies can sometimes lead to male calicos, but they're estimated to be just 1 in 3,000 calico cats! If you ever come across a male calico, consider it a lucky encounter, but remember, regardless of its rarity, every cat deserves a loving and caring home.
