What is the Cat Pregnancy Calculator?

The Cat Pregnancy Calculator is a simple tool that helps cat owners estimate key stages of their cat’s pregnancy. By entering the mating date, the calculator predicts important milestones such as implantation, heartbeat detection, and the due date.

How the Calculation Works

The calculator estimates the pregnancy timeline based on an average gestation period of 63-67 days, with most cats delivering around day 65. Different breeds may have slightly varying pregnancy durations.

Due Date Formula:

\[ \text{Due Date} = \text{Mating Date} + \text{Gestation Period} \]

Each milestone in the pregnancy is estimated using this method:

  • Implantation: Around 5-6 days after mating.
  • Heartbeat Detection: Around 20 days after mating.
  • Halfway Point: Half of the total pregnancy duration.
  • Optimal Ultrasound Timing: Around 42 days after mating.
  • Nesting Behavior: About 1 week before delivery.

Using the calculator is quick and easy. Follow these steps:

  1. Select the mating date in the input field.
  2. Choose your cat’s breed type from the dropdown menu.
  3. Click the “Calculate” button.
  4. View the estimated pregnancy timeline with key dates.
