Rabbit Gestation Calculator

Frequently Asked Questions

How long is a rabbit pregnant?

Rabbit gestation is 28-33 days depending on breed size. Small breeds like Netherland Dwarfs tend toward the shorter end (28-30 days), medium breeds like New Zealands average 30-32 days, and large breeds like Flemish Giants run 31-33 days. Birth (kindling) is often quick, with the entire litter delivered within 30 minutes.

When should I put a nesting box in the cage?

Place a nesting box in the cage around day 28 of pregnancy, even for breeds with shorter gestations. Does typically begin pulling fur from their belly and dewlap to line the nest 1-3 days before kindling. Providing the box early gives her time to prepare.

Can rabbits get pregnant again immediately after kindling?

Yes - does can be bred again within hours of giving birth (postpartum estrus). Back-to-back breeding is hard on the doe and is generally not recommended for pet rabbits. Most breeders wait 4-6 weeks after kindling before re-breeding to allow the doe to recover and wean the current litter.

How This Calculator Works

Rabbit gestation is very short - typically 28 to 33 days - and varies 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 two-day 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 dam's age.

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 - no 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

Unlike dogs and cats, rabbit kindling is typically very fast - most does deliver all kits within 30 minutes and often in the early morning hours. Signs that kindling is imminent include:

Intense fur pulling - lining the nest box with fur from her own belly and dewlap.

Restlessness and rearranging bedding.

The doe entering and leaving the nest box repeatedly.

Visible abdominal movement as kits shift position.

Do not disturb the doe during and immediately after kindling. Stress can cause a doe to abandon or injure her kits.

Caring for Newborn Kits

Newborn kits are born hairless, blind, and deaf. They are completely dependent on the doe for warmth. Key points:

Nursing: Does typically nurse only once or twice per day, usually at night. Brief visits are normal - a doe sitting in the box all day is not typical.

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

Check daily: Gently check that kits are warm, round-bellied (fed), and moving. Remove any stillborn kits promptly.

Hands and scent: Does generally do not reject kits due to human scent, so brief daily checks are fine.

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 (not fed) 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 (signs of infection or retained kits).

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