Table 1: Average Gestation Periods for Domestic Cats by Breed
| Breed | Average Gestation (Days) | Gestation Range (Days) | Notes |
|---|---|---|---|
| Domestic Shorthair | 65 | 63 – 67 | Most common breed, standard gestation |
| Siamese | 64 | 62 – 66 | Slightly shorter gestation |
| Maine Coon | 66 | 64 – 68 | Larger breed, slightly longer gestation |
| Bengal | 65 | 63 – 67 | Similar to domestic shorthair |
| Persian | 65 | 63 – 67 | Longer hair breed, standard gestation |

Essential Formulas for Cat Pregnancy Calculator
Calculating the expected delivery date (EDD) and gestational age requires precise formulas. Below are the key formulas used in cat pregnancy calculations, styled for WordPress.
1. Expected Delivery Date (EDD) Calculation
- EDD: Expected Delivery Date (date)
- Date of Mating: The date when mating occurred (date)
- Average Gestation Period: Typically 65 days for domestic cats (days)
This formula assumes fertilization occurs on the mating date. If conception date is known, replace “Date of Mating” with “Date of Conception”.
2. Gestational Age Calculation
- Gestational Age: Number of days since mating (days)
- Current Date: Date of calculation (date)
- Date of Mating: Date when mating occurred (date)
Gestational age helps determine fetal development stage and estimate time remaining until birth.
3. Estimating Gestational Age from Fetal Size (Ultrasound)
Fetal size measured via ultrasound can estimate gestational age using linear regression derived from veterinary studies:
- Fetal Size: Crown-rump length or fetal length measured by ultrasound (cm)
- Gestational Age: Estimated days since conception (days)
This formula is an approximation and should be used alongside clinical judgment.
4. Days Remaining Until Delivery
- Days Remaining: Number of days until expected delivery (days)
- Average Gestation Period: Typically 65 days (days)
- Gestational Age: Days since mating or conception (days)
Negative values indicate the cat is overdue and may require veterinary attention.
Detailed Real-World Examples of Cat Pregnancy Calculator
Example 1: Calculating Expected Delivery Date from Mating Date
Scenario: A domestic shorthair cat mated on March 1, 2024. Calculate the expected delivery date.
- Date of Mating = March 1, 2024
- Average Gestation Period = 65 days (standard for domestic shorthair)
Step 1: Convert the date to a numerical format or use a date calculator.
Step 2: Add 65 days to March 1, 2024.
March 1 + 65 days = April 30, 2024
Result: The expected delivery date is April 30, 2024.
Example 2: Estimating Gestational Age from Ultrasound Fetal Size
Scenario: On April 15, 2024, an ultrasound shows a fetal size of 2 cm. Estimate the gestational age and expected delivery date.
- Fetal Size = 2 cm
- Average Gestation Period = 65 days
- Ultrasound Date = April 15, 2024
Step 1: Calculate gestational age using the formula:
Step 2: Calculate estimated conception date:
Conception Date = Ultrasound Date – Gestational Age = April 15, 2024 – 30 days = March 16, 2024
Step 3: Calculate expected delivery date:
EDD = Conception Date + 65 days = March 16, 2024 + 65 days = May 20, 2024
Result: The cat is approximately 30 days pregnant, with an expected delivery date of May 20, 2024.
Additional Technical Details and Considerations
- Variability in Gestation Length: While 63-67 days is typical, factors such as breed, litter size, and maternal health can influence gestation length.
- Ultrasound Accuracy: Early ultrasounds (before day 20) may not detect pregnancy; fetal size measurements become more reliable after day 25.
- Palpation: Manual abdominal palpation can detect fetuses between days 17-25 but is less precise than ultrasound.
- Hormonal Testing: Progesterone levels can assist in confirming pregnancy and estimating timing but require veterinary lab analysis.
- Overdue Pregnancies: If gestation exceeds 70 days, veterinary consultation is essential to rule out complications.
