Rabbit Pregnancy Timeline
Pre-Birth Phase
Breeding Day
The day you breed your rabbit. Does typically reach sexual maturity at 4-6 months, while bucks reach maturity at 6-10 months depending on breed size.
Palpate
Gently press the doe's abdomen to feel for developing kits. This confirms pregnancy and helps plan for the litter. Be careful not to apply too much pressure.
Nestbox & Nails
Prepare the nestbox with clean bedding and hay. Trim the doe's nails to prevent accidental injury to the kits during and after birth.
Due Date
Expected kindling day. Watch for signs of labor: fur pulling, nesting behavior, loss of appetite, mood changes. Rabbits typically give birth quickly, often within minutes.
Post-Birth Phase
Eyes Open
Kits' eyes begin to open. Check that all kits have round tummies (indicating they're being fed). Contact a vet if you suspect nursing issues.
Flip Nestbox & Sanitize
Turn the nestbox over to refresh bedding and clean the cage thoroughly. Kits are becoming more active and exploring their environment.
Remove Nestbox
Kits are mobile enough to leave the nestbox. Remove it and sanitize the entire cage. Kits may start nibbling on hay and pellets.
Sort Litter
Evaluate the litter for size, health, and temperament. Separate by sex if needed. Start planning for weaning and placement.
Wean Litter
Kits can be fully weaned at 8 weeks. Feed unlimited pellets and hay, but avoid vegetables and treats until their digestive systems mature.
Complete Guide to Rabbit Pregnancy and Breeding
Understanding Rabbit Gestation
Rabbit gestation averages 31 days, making rabbits one of the fastest-reproducing mammals kept by breeders. The normal range spans 28 to 35 days, though most does kindle right around day 31 or 32. This rabbit gestation calculator uses the standard 31-day period to generate your full pregnancy timeline automatically.
Several factors influence the exact delivery date. Larger breeds like Flemish Giants and Continental Giants tend to carry a day or two longer than smaller breeds like Netherland Dwarfs or Mini Rex. First-time mothers (primiparous does) sometimes go a day late as well. Larger litters often arrive slightly earlier because the uterus reaches capacity sooner.
If your doe passes day 35 without kindling, contact your veterinarian. Prolonged pregnancy can indicate a single oversized kit, a deceased litter, or a false pregnancy. On the other end, kits born before day 28 may be premature and need extra warmth and monitoring.
How to Confirm Rabbit Pregnancy
Palpation is the most reliable way to confirm pregnancy in rabbits. Between days 10 and 14 after breeding, you can feel grape-sized embryos in the doe's lower abdomen. Here is how to palpate safely:
- Restrain the doe gently on a flat surface or hold her securely with one hand supporting her chest.
- Slide your other hand under her belly, just in front of the pelvis.
- Use your thumb and fingers to gently roll the tissue between them. Developing embryos feel like small, firm marbles in a row.
- Compare both sides of the uterus. You should feel similar-sized lumps on each uterine horn.
Other pregnancy signs to watch for in later weeks include increased appetite, digging behavior, irritability when the buck is nearby, and visible weight gain around the belly. In the final days, the doe will pull fur from her chest and dewlap to line the nest.
Choosing the Right Rebreed Schedule
Your rebreed schedule directly affects how many litters a doe produces per year and her long-term health. The three most common cycles are:
| Cycle | Rebreed After | Litters/Year | Best For |
|---|---|---|---|
| 45-Day (Intensive) | 14 days post-kindle | ~8 | Meat production, commercial operations |
| 60-Day (Moderate) | 28 days post-kindle | ~6 | Most hobby breeders, balanced approach |
| 90-Day (Relaxed) | ~60 days post-kindle | ~4 | Show breeders, doe recovery priority |
Most hobby breeders find the 60-day cycle works best. The doe weans her current litter at 8 weeks (day 56), gets a few days of rest, and is rebred around day 60. This gives her body time to recover while maintaining steady production.
The 45-day cycle is used in commercial meat operations where does are rebred while still nursing. This is physically demanding and shortens a doe's productive lifespan. We do not recommend it unless you are experienced and providing optimal nutrition.
The 90-day cycle is ideal for show breeders who prioritize the doe's condition over litter frequency. Does on this schedule stay in better body condition and tend to produce larger, healthier litters when they do breed.
Preparing the Nestbox for Kindling
A properly prepared nestbox is critical for kit survival. Place it in the cage on day 27 of pregnancy. Adding it earlier often results in the doe using it as a litter box.
Nestbox Size by Breed
| Breed Size | Nestbox Dimensions | Example Breeds |
|---|---|---|
| Small (under 5 lbs) | 14" x 8" x 7" | Netherland Dwarf, Mini Rex, Holland Lop |
| Medium (5 to 10 lbs) | 18" x 10" x 9" | Rex, Californian, New Zealand |
| Large (over 10 lbs) | 22" x 12" x 10" | Flemish Giant, French Lop, Continental |
Nestbox Setup Checklist
- Line the bottom with a layer of wood shavings (not cedar) for absorption
- Pack the box with clean hay or straw, filling it about 3/4 full
- Create a small hollow in the center where the doe can arrange her nest
- Trim the doe's nails on the same day to prevent accidental scratches to newborn kits
- In cold weather, add extra bedding and consider placing the nestbox in a draft-free corner
Caring for Newborn Rabbit Kits
Newborn rabbit kits are born hairless, blind, and completely dependent on their mother's milk. The first 48 hours are the most critical period. Here is what to do after kindling:
First 12 Hours
Check the nestbox for dead or scattered kits. Count the litter, remove any stillborns, and ensure all living kits are covered with fur. Do not disturb the doe more than necessary.
Day 1 to 3
Check kit bellies daily. A fed kit has a round, white belly visible through the skin. Sunken or wrinkled bellies mean the kit is not nursing. The doe only feeds once or twice per day, usually at dawn and dusk.
Day 10 to 14
Eyes begin opening around day 10. By day 14, all kits should have open eyes. If an eye appears sealed shut or swollen, gently clean it with warm saline to prevent infection.
Day 21+
Kits start leaving the nest and nibbling on hay and pellets. Remove the nestbox, deep-clean the cage, and ensure fresh water is accessible at kit height. They still nurse alongside solid food.
Common Rabbit Pregnancy Problems
False Pregnancy (Pseudopregnancy)
A doe can exhibit all the signs of pregnancy, including nesting, fur pulling, and aggression, without actually being pregnant. False pregnancies happen when ovulation is triggered by mounting (even from another doe) without fertilization. They typically last 16 to 18 days. The doe will build a nest, then lose interest. You can safely rebreed her once the behavior stops.
Kindling Problems
| Problem | Signs | Action |
|---|---|---|
| Scattered kits | Kits born outside the nestbox | Gather kits into the nest, cover with fur, keep warm |
| Retained kit | Doe straining after delivery, visible distress | Veterinary emergency. May need oxytocin or manual extraction |
| Cannibalism | Doe eats one or more kits | Often a first-time mother issue. Ensure quiet environment, adequate nutrition, and fresh water |
| Mastitis | Hot, swollen, or discolored mammary glands | Veterinary treatment required. Antibiotics and anti-inflammatories needed |
When to Call the Vet
- No kindling by day 35
- Active straining for more than 30 minutes without producing kits
- Bloody or foul-smelling discharge after kindling
- Doe refuses food or water for more than 24 hours post-kindling
- Red, hot, or hard mammary glands
Weaning and Litter Management
Weaning is the process of transitioning kits from mother's milk to solid food. In domestic rabbits, this happens gradually between weeks 4 and 8, with full separation at 8 weeks (56 days).
Week-by-Week Weaning Timeline
| Age | What Is Happening | Breeder Action |
|---|---|---|
| Week 3 | Kits start nibbling hay and pellets | Remove nestbox. Ensure food and water are at kit level |
| Week 4 | Solid food intake increases, still nursing | Provide unlimited pellets and hay for kits and doe |
| Week 5 | Sort litter by sex. Evaluate for keepers | Separate bucks from does if early developers are noticed |
| Week 6-7 | Kits eating mostly solid food, nursing decreases | Monitor growth rates. Identify runts that need extra care |
| Week 8 | Full weaning | Separate kits from doe. Move to grow-out cages. Doe rests before rebreed |
Frequently Asked Questions
How long is a rabbit pregnant?
Rabbit gestation averages 31 days, with a normal range of 28 to 35 days. Most does kindle on day 31 or 32. Larger breeds may carry a day longer, and larger litters sometimes arrive a day early. If your doe passes day 35 without kindling, contact your veterinarian immediately.
When should I put the nestbox in?
Place the nestbox in the cage on day 27 of pregnancy, four days before the expected due date. Adding it earlier increases the chance the doe will soil it. Fill it with clean hay or straw, and trim the doe's nails on the same day to protect the kits from accidental scratches.
How can I tell if my rabbit is pregnant?
Palpate the doe between days 10 and 14 after breeding by gently feeling her lower abdomen for small, grape-sized lumps. Later signs include increased appetite, nesting behavior, digging, irritability, and fur pulling in the final days before kindling.
Can rabbits get pregnant again right after giving birth?
Technically yes. Rabbits are induced ovulators and can become pregnant immediately after kindling. However, rebreeding too soon is stressful and shortens the doe's productive life. We recommend waiting at least 14 days (45-day cycle) to 4 weeks (60-day cycle) before rebreeding.
When can baby rabbits leave their mother?
Baby rabbits should stay with their mother until at least 8 weeks (56 days) of age. By this time, they are fully weaned, eating solid food independently, and have developed the gut flora needed to digest hay and pellets. Separating kits earlier increases the risk of enteritis.
What do I do if a kit is scattered outside the nestbox?
Scattered kits happen, especially with first-time mothers. Pick the kit up, warm it in your hands if it feels cold, and place it back in the nest. Cover it with pulled fur. Check on the litter more frequently for the next 24 hours. If the doe repeatedly scatters kits, she may need a more confined nestbox.
