Queen pregnancy calculator

This cat pregnancy calculator helps you work out when your pregnant cat is due by using the date of first mating. Simply enter the mating date to calculate your cat’s estimated due date, pregnancy length, and key milestones throughout her pregnancy. Cats are typically pregnant for around 63–67 days, but every queen is different. This pregnant cat due date calculator provides a clear guide to help you understand how far along your cat is, what stage of pregnancy she is in, and what to expect as her due date approaches.
