Milk is bad for rabbits

Milk is not a natural part of a rabbit's diet and can cause digestive upset and other health issues if given to rabbits. Here's why you should avoid giving any type of milk to rabbits:

  • Lactose Intolerant – Rabbits do not produce enough of the enzyme lactase to properly digest lactose, the sugar found in milk. Lactose intolerance can cause diarrhea, gas, and abdominal pain.
  • High Fat Content – The high fat content of milk can also lead to digestive upset and potentially obesity if fed regularly. Rabbits are herbivores meant to process plant-based diets lower in fat.
  • Allergy Risk – Cow's milk is a common allergen for rabbits. An allergic reaction can cause swelling, itching, gastrointestinal issues and breathing problems.
  • Harmful Bacteria – Unpasteurized milk may contain listeria or other bacteria that can make rabbits very ill. Always avoid unpasteurized dairy.
  • Nutritional Imbalance – Milk provides nutrients like protein and calcium but in improper ratios for a rabbit's needs. Too much calcium or protein stresses the kidneys and urinary tract.
  • Dehydration – The proteins, fat, and lactose in milk can actually leach water from the intestines and lead to dangerous dehydration.
  • Obesity – Milk has more calories and fat compared to the diet a rabbit naturally eats. Weight gain stresses the bones and organs.

For all these reasons, veterinarians strongly advise against giving any type of milk to pet rabbits. Milk products made for human consumption have no place in a rabbit diet and pose many risks to your bunny's digestive health. Rabbits have no need to consume milk after weaning. Their bodies are simply not adapted to process milk properly.

Oh no! My rabbit just drank a little bit of milk

If your rabbit accidentally consumed a small amount of milk, do not panic. Monitor your rabbit closely for any signs of intestinal upset or allergic reaction. Here are some steps to take:

  • Encourage him to drink extra water to help dilute the milk. Add more fresh greens to encourage hydration through the diet.

  • Limit pellets and treats for the next 12 hours to allow the GI tract to rest. Continue offering hay which should make up the bulk of diet.

  • Watch for diarrhea, lack of appetite, lethargy or swelling which can indicate an allergic reaction. Call your vet if you observe any of these symptoms.

  • Avoid any other new foods or stressful situations which could make intestinal issues worse. Stick to your rabbit's normal routine.

  • If diarrhea lasts more than 24 hours or is extremely watery, call your veterinarian for an appointment and bring a fecal sample. Your rabbit may need medication or subcutaneous fluids to prevent dangerous dehydration.

  • Monitor urine output and litter habits closely. Any signs of decreased urination, straining, or bladder sludge require an urgent vet visit as milk can sometimes cause GI stasis or urinary blockages.

  • Once your rabbit's digestion normalizes, continue as usual with their normal diet and exercise. Avoid milk in the future!

With prompt care and monitoring, a small amount of milk is unlikely to cause lasting harm. But it's still best to avoid milk to keep your rabbit healthy and happy.

Water is the best for rabbits

The number one beverage your rabbit needs is simple, plain water. Why is water so important for rabbits?

  • Prevents Dehydration – Rabbits have a higher risk of dehydration since they get much of their water needs met through food. Clean water prevents dangerous water loss.
  • Supports Digestion – Water softens food in the gut, allowing it to pass easily. This prevents issues like GI stasis.
  • Flushes Out Bacteria – Adequate hydration allows more frequent urination which flushes out harmful bacteria.
  • Aids Circulation – Water supports blood volume, blood pressure and heart health.
  • Regulates Body Temperature – Water helps rabbits cool down since they can't sweat like humans. This prevents overheating.
  • Keeps Eyes, Nose Moist – Water keeps mucous membranes hydrated for immune function.

Make sure your rabbit's water bowl or bottle is kept freshly cleaned and filled at all times. Change the water at least once daily. Frequent refilling and washing prevents bacteria or mold from accumulating. Avoid flavored waters or additions beyond a daily multivitamin. Stick to plain, filtered water for the optimal hydration.

How much water do rabbits need

The typical rabbit drinks 50-100 mL per kg body weight per day. That translates to:

  • Small rabbit (2 kg) – 100 to 200 mL daily
  • Medium rabbit (4 kg) – 200 to 400 mL daily
  • Large rabbit (6+ kg) – 300 to 600+ mL daily

However, water needs vary greatly by the rabbit's diet, exercise level, housing temperature, and health status. Some general tips for meeting your rabbit's hydration needs:

  • Unlimited clean water should always be available 24/7

  • Housing over 75°F may double water requirements

  • High vegetable or pellet diets increase water needs

  • Nursing does require additional water for milk production

  • Outdoor rabbits need extra water in hot or cold weather

  • Senior rabbits tend to drink more water

  • Ill rabbits need easy water access during recovery

Monitor your rabbit's water intake daily. Increased thirst may signal a health issue requiring veterinary attention. Decreased water consumption is an emergency requiring immediate fluid therapy. Ensure multiple bowls are located in exercise areas for reminder hydration. Support your rabbit's water needs to maintain good health.

Water bottle vs. water bowl

Both water bottles and bowls have pros and cons for rabbits:

Water Bottles:

  • Leak-proof, limit messes
  • Familiar to caged rabbits
  • Promote hydration with constant access
  • Require regular cleaning to prevent blockages

Water Bowls:

  • Allow rabbits to drink more at once
  • Easier to monitor water intake
  • Preferred by some rabbits
  • Can tip and spill easily

To decide between a bottle or bowl, consider your rabbit's housing, preferences, and health needs. Bowls allow more natural drinking but require careful monitoring. Bottles are more physically restrictive but stay cleaner for compromised rabbits.

For most house rabbits, bowls are preferred as the wider opening and water volume mimics natural hydration. Provide multiple bowls aroundexercise areas. Switch to a bottle for sick or disabled rabbits struggling to reach a bowl. Avoid bottles for rabbits with respiratory infections as sucking can exacerbate problems.

With either option, wash and refresh water twice daily minimum. Make sure water is always plentiful, clean and available to support your rabbit's needs. Monitor intake and health, changing format if issues arise.

Excessive thirst or not drinking at all

Sudden increases or decreases in your rabbit's water consumption can signal an urgent health issue requiring veterinary attention. Monitor water intake daily. Watch for these red flags:

Excessive Thirst:

  • Doubling of normal water intake
  • Difficulty staying hydrated
  • Urinating more frequently
  • Damp face from excess drinking

Causes can include diabetes, kidney disease, chewing disease, heat stress, pregnancy, or high pellet/veggie diet.

Not Drinking:

  • No interest in water
  • Smaller, darker urine amounts
  • Dry sticky poops
  • Skin tenting from dehydration

This life-threatening emergency is usually caused by GI stasis, oral pain, or major infection.

If you notice either excess thirst or no water consumption, get emergency vet care right away. Bring a water sample for urinalysis. Underlying issues likeUTIs or kidney failure require diagnosis and prompt treatment. Don't delay – sudden hydration changes in rabbits are medical emergencies requiring urgent response. With supportive therapy from your exotic vet, most rabbits can recover and stabilize with close monitoring after the underlying cause is found. Don't take chances with your bunny's water intake!

Other liquids rabbits can drink

While water should make up the bulk of fluid intake, some other liquids are fine for rabbits in moderation.

Fruit/Vegetable Juice:
The extra hydration and nutrients from small amounts of 100% juice can benefit sick or underweight rabbits, but only if recommended by a vet. Limit to 1-2 teaspoons daily. Too much natural sugar can cause GI issues. Never give human juice drinks.

A teaspoon of unsalted broth added to water can encourage drinking, but should not replace regular water. Make sure the broth has no onion or garlic which are toxic to rabbits. Limit use unless recommended by your vet.

Herbal Tea:
Caffeine-free herbal teas like chamomile, mint, and lemon balm are safe if given sparingly. They can provide gentle anti-inflammatory effects. Limit to 1-2 teaspoons diluted in water as too much can cause diarrhea.

Flower Essences:
A couple drops of gentile flower essences like Bach Rescue Remedy added to water can help calm anxious or stressed rabbits. Use only as directed and stop if any diarrhea develops.

Avoid sodas, flavored drinks, alcohol or any liquids with sugars, artificial ingredients or carbonation which can all cause digestive upset in rabbits. Always clear any new supplements, herbs or liquids with your vet before giving to make sure they are safe.

Flavoring water

If your fussy rabbit refuses plain water, a vet may recommend adding flavorings to encourage drinking. Use healthy rabbit-safe options only under your vet's guidance. Some choices include:

  • A teaspoon of 100% apple or pineapple juice

  • Several sprigs of mint from your garden

  • Slices of lemon, lime or orange

  • A drop of all-natural extract like vanilla or almond

  • A few fresh or dried flowers like hibiscus or rose petals

  • Clear low-sugar broths

  • Diluted chamomile, mint or lemon balm tea

Rotate flavors periodically to keep interest. Always use human-grade ingredients and thoroughly wash produce. Stop if soft stools develop. Avoid any flavorings with artificial ingredients, sugars or preservatives.

The goal is to supplement just enough taste to stimulate water intake, without relying long-term on flavor additions. Monitor your rabbit’s water consumption closely. Work with your vet to slowly taper flavorings and transition back to plain water as health allows. With patience, most rabbits will learn to accept a healthy water regimen.

Teas that are okay for a rabbit to drink

Herbal teas can provide some beneficial hydration, nutrients and minerals for rabbits in small amounts. Limit 1-2 teaspoons diluted in water once or twice a week. Safe, gentle herbals teas include:

  • Chamomile – Calming, aids digestion/appetite

  • Peppermint – Settles GI tract, freshens breath

  • Lemon balm – Reduces stress/tension, antiviral

  • Rosehip – Immune boosting vitamin C

  • Dandelion – Cleansing for liver and urinary tract

  • Rose petals – Soothing and hydrating

  • Calendula – Anti-inflammatory, eases skin irritation

  • Fennel – Digestive aid and gas relief

Avoid flavored teas with oils, sugars or additives. Introduce new flavors slowly watching for diarrhea. Only provide teas occasionally but rotate types for variety. Make sure the tea is lukewarm to prevent mouth burns. Herbal teas can supplement a rabbit’s primarily water-based fluid intake when used judiciously.

Yogurt treats

Plain yogurt can be a healthy occasional treat for rabbits in very small portions, as long as they tolerate dairy. Limit to 1⁄2 teaspoon per 2 lbs body weight, selecting an unsweetened yogurt.

Look for brands with live active cultures to support digestive health. Try Greek yogurt which is higher in protein and lower in carbs. Avoid yogurt with artificial sweeteners.

Feed yogurt as an infrequent treat no more than 1-2 times per week. Due to the lactose and sugar content, yogurt risks digestive upset if fed in excess. Make sure your rabbit's normal diet includes lots of grass hay, veggies, and water.

Yogurt's probiotics and moisture can benefit some rabbits prone to soft stools or GI issues. Always monitor stool consistency when introducing new foods. Discontinue yogurt if soft stools result.

Plain organic yogurt, given sparingly, can offer rabbits a nutritious calcium and protein boost. Just a dab will give your bunny a yogurt taste experience without taxing their delicate digestive system.

Should baby rabbits have milk?

Mother’s milk provides the perfect nutrition baby rabbits need in their first weeks of life. But if bunnies are orphaned, cow’s milk or kitten formula are unsuitable replacements that can quickly turn deadly. Here’s how to feed baby rabbits if no mother is present:

Avoid Cow's Milk – The proteins, fat, and lactose make cow’s milk very difficult for rabbits to digest. Diarrhea, gas, and gut stasis often develop.

Avoid Kitten Formula – Kitten milk replacers still contain too much protein and fat for baby rabbits. Life-threatening diarrhea results.

Make a Benebac/KMR/Colostrum Mix – Mix non-fat, plain yogurt with a probiotic (Benebac), kitten milk replacer (KMR) and bovine colostrum for a nutritionally balanced rabbit milk.

Bottle Feed on Schedule – Use kitten bottle feeding techniques but with the rabbit milk mix. Keep feedings spaced consistently around the clock.

Transition to Solids – Slowly introduce timothy hay, greens and appropriately portioned pellets around 3-4 weeks old as bunnies naturally wean.

Continue Probiotics – Probiotic powder on foods prevents disruption to gut microflora during periods of change.

Orphaned bunnies have very specific nutritional needs. Work closely with an experienced wildlife rehabilitator or exotic veterinarian to ensure baby rabbits receive an appropriate formula and proper care as they grow. With a specialized feeding protocol, orphaned baby rabbits can survive and thrive.

Milk alternatives for orphaned baby rabbits

If you need to hand raise an orphaned baby rabbit, use the following milk alternative recipe on the instruction of an exotic vet or wildlife rehabilitator:


  • Goat or sheep milk formula – better digested than cow milk
  • Colostrum – for immunity boost
  • Probiotic powder – maintains healthy gut
  • Kitten milk replacer – nutrition/electrolytes


  • 2 parts goat or sheep milk formula
  • 1 part bovine colostrum
  • 1 part kitten milk replacer
  • 1⁄4 teaspoon probiotic powder per portion

Slowly transition this formula to vegetables, hay and pellets around 3-4 weeks old as their digestive system matures. Careful hand raising of orphaned rabbits requires specific techniques but supports healthy development so they can eventually live happy, normal lives. Consult qualified exotic veterinarians to ensure your orphaned bunnies thrive.
