How to read the ferret gestation chart
Find the row closest to the date the ferret was served. The right-hand column is the expected kindling date at 42 days. Because normal gestation spans 38 to 44 days, plan for a window of a few days either side of that date. For a date that is not on the grid, use the calculator below.

Ferret gestation chart FAQs
How long is a ferret pregnant?
About 42 days — six weeks — with almost all jills kindling between 38 and 44 days. Ferret gestation is one of the most predictable of any small pet.
How do I know it is a real pregnancy and not a false one?
Ultrasound from about day 12 to 14. False pregnancies in ferrets run the full six weeks with nest building and mammary development, so behaviour and shape alone are not proof.
Why is leaving a jill in season without mating dangerous?
Prolonged oestrogen exposure suppresses the bone marrow and causes aplastic anaemia, which can be fatal. Any jill not being bred should be spayed or managed with a hormone implant rather than left in season.
What should a pregnant ferret eat?
A high-protein, high-fat diet — a kit or breeding formulation — available constantly rather than in set meals. Her intake can rise sharply in the last two weeks, and running out of food even briefly raises the risk of pregnancy toxaemia.
What do I need to have ready before kindling?
A dark, enclosed nest box with soft bedding in a quiet, warm room, food and water she cannot empty, and no cage changes from about day 35. Handle her as little as possible and let her arrange the nest herself.
When do ferret kits open their eyes and get weaned?
Eyes open at roughly three to five weeks, much later than most small pets. They start on solid food around three to four weeks and are usually fully weaned by six to eight weeks.
