Ferret pregnancy guide
How long is a ferret pregnant?
A ferret is pregnant for about 42 days. The normal range is 39 to 44 days, so most kits arrive within that window rather than on the exact average day.
Quick rule: Count 6 weeks forward from the mating date. The kindling window runs from day 39 to day 44.
How to use the ferret pregnancy calculator
1. Enter the mating date. The day she mated with the hob. Tap Use today if it was today.
Then follow the schedule. Each task gets a real date, the next one is highlighted, the status shows whether your jill is on track, and the week by week cards above show where things stand. Use Copy schedule or Add to Google Calendar to keep it.
Gestation formulas
- Estimated kindling date = mating date + 42 days
- Earliest normal kindling = mating date + 39 days
- Latest normal kindling = mating date + 44 days
- Breed adjustment = breed average minus 42 days, applied to the whole window
- Call your vet if nothing has happened by day 44
Care schedule for a pregnant jill
