No, calico cats are not always female. Calico cats have a coat pattern that consists of three colors: white, black, and orange. The gene for coat color is located on the X chromosome, and in most cases, female cats have two X chromosomes, while males have one X and one Y chromosome. This means that in order for a male cat to be calico, it would need to have an extra X chromosome, a rare genetic anomaly. Therefore, calico cats are almost always female, but there are rare cases of male calico cats. **

The credit line is determined by the credit card issuer based on the cardholder's credit history and income. As the cardholder makes payments and reduces the balance, the available credit increases, and they can continue to make purchases up to the credit limit. **
