Rabbit Gestation Calculator

Frequently Asked Questions

How long is rabbit gestation?

Rabbit gestation ranges from 28 to 33 days depending on breed size. Small breeds (Netherland Dwarf, Holland Lop) typically kindle around day 29; medium breeds (New Zealand, Rex) around day 31; large breeds (Flemish Giant, French Lop) around day 32. A doe that has not kindled by day 34 should be seen by a veterinarian.

Can a rabbit have a false pregnancy?

Yes. Pseudopregnancy (false pregnancy) can occur in does when ovulation is triggered by a sterile mating, the presence of a buck, or even mounting by another doe. It typically lasts 16-17 days and can include nest-building behavior and fur pulling despite no live kits being present.

Why does the doe only nurse once or twice a day?

Rabbit milk is extremely rich and calorie-dense, so kits are fully satisfied from very brief nursing sessions (often just 5 minutes). Wild rabbits also evolved to minimize time in the nest to avoid attracting predators. The doe not sitting in the nest box all day is normal - check that kits have round, full bellies rather than watching for the doe to nurse.

When should I separate the kits from the doe?

Kits are typically weaned at 6-8 weeks. Does can be rebred as early as 6-8 weeks postpartum, though allowing 8-10 weeks between litters supports better health for both doe and kits. Never wean kits before 6 weeks - early weaning increases mortality and digestive disease risk.

How This Calculator Works

Rabbit gestation is very short - typically 28 to 33 days - and varies slightly by breed size. Small breeds (under 4 lb) tend to kindle at the shorter end of the range while large breeds run a day or two longer. This tool uses the midpoint for your selected size class and adds it to the breeding date to produce an expected kindling date and a window on each side.

Because rabbit gestation is so brief, timing preparation is critical: the nest box must be in place by day 14 so the doe has time to build her nest before kindling.

Rabbit Gestation Facts

Small breeds (e.g. Netherland Dwarf, Holland Lop): 28-30 days, midpoint 29 days.

Medium breeds (e.g. New Zealand, Rex): 30-32 days, midpoint 31 days.

Large breeds (e.g. Flemish Giant, French Lop): 31-33 days, midpoint 32 days.

Litter size: typically 4-10 kits depending on breed and the doe's age and condition.

Does are induced ovulators: ovulation occurs 10-13 hours after mating, so a successful breeding almost always results in conception.

False pregnancy (pseudopregnancy): can last 16-17 days and mimic true pregnancy symptoms including nest building.

Nest Box Timing

Place the nest box in the doe's cage on day 14 - not earlier, as too much time with the box can cause the doe to use it as a litter tray. Fill it loosely with clean hay or straw. Many does begin pulling fur from their dewlap and belly around day 25-28 to line the nest. A doe that pulls fur and has no box may scatter it and fail to build a proper nest, leading to kit mortality.

Nest box dimensions should allow the doe to turn around comfortably but be snug enough to keep kits warm. A solid floor with 2-3 inches of bedding below the hay layer works well.

Signs of Labor and Newborn Kit Care

Unlike dogs and cats, rabbit kindling is typically very fast - most does deliver all kits within 30 minutes, often in the early morning hours. Signs that kindling is imminent include intense fur pulling, restlessness, and the doe entering and leaving the nest box repeatedly.

Newborn kits are born hairless, blind, and deaf. Key care points:

Nursing: does typically nurse only once or twice per day, usually at night. Brief visits are normal.

Warmth: keep the nest box at 65-70°F ambient. Kits huddle together and the fur lining insulates them.

Daily check: gently confirm kits are warm, round-bellied (fed), and moving. Remove any stillborn kits promptly.

Eyes open: around day 10-12. Kits begin exploring outside the nest box around day 18-20.

Weaning: typically at 6-8 weeks.

When To Worry

Kindling has not occurred by day 34 - contact your vet as prolonged gestation can indicate a dead litter requiring intervention.

Kits feel cold and limp - warm them gently in your hands; cold kits can often be revived if found quickly.

Kits have wrinkled, loose skin after 24 hours - the doe may not be nursing.

The doe is off food, lethargic, or has a bloody or foul-smelling vaginal discharge after kindling.

Mastitis - a hot, hard, discolored mammary gland - requires immediate veterinary attention.
