What Are Collard Greens?

Collard greens are a cultivar of the species Brassica oleracea and are part of the cabbage family. They are a cool season crop and are considered a leaf vegetable. Collard greens have broad, dark blue-green leaves that are thick and smooth in texture. Unlike other cabbage relatives that form tight heads, collard leaves grow in loose rosette formations. Each leaf emerges from a central stalk that can grow upwards of 2 feet tall. Collard greens likely originated in the Mediterranean region over 2,000 years ago but are now grown worldwide. They thrive in cool climates and are especially popular in Brazilian, Portuguese, Indian, and various African cuisines. In the American South, collard greens are a staple side dish, typically braised with smoked pork. The leaves have a slightly bitter, earthy flavor that becomes more mellow when cooked. Collards are highly nutritious, providing vitamin C, vitamin K, vitamin A, calcium, iron, magnesium, and potassium. They also contain compounds like sulforaphane that may have anticancer effects. Collard greens are available year-round but reach peak season from January through April. When shopping, look for crisp green leaves without any yellowing or wilting. Store unwashed collard greens in a loose plastic bag in the refrigerator for 3-5 days.

Are Collard Greens Good for Rabbits?

Yes, collard greens are perfectly safe and even beneficial for rabbits to eat. Here's an overview of their nutritional value:

  • High in fiber – The indigestible parts of collard greens are an excellent source of dietary fiber. This helps promote healthy digestion and gut motility in rabbits.

  • Rich in vitamin K – Collards contain exceptionally high levels of vitamin K. This vitamin is essential for proper blood clotting and bone metabolism in rabbits.

  • Source of calcium – Collard greens provide a bioavailable form of calcium which is necessary for building strong bones and teeth.

  • Antioxidants – Collards contain antioxidants like vitamin C, beta-carotene, and manganese that support the immune system and fight disease.

  • Low in fat and calories – With almost no fat and minimal calories, collards are great for weight management.

The high moisture and low calorie content also make collard greens useful for hydration. The only downside is that collards contain oxalic acid which can potentially bind to calcium. However, the levels are not significant enough to worry about for healthy adult rabbits.

How Much Veg Can My Rabbit Eat?

When giving collard greens to a rabbit, moderation is key. Here are some guidelines on how much to feed:

  • Introduce collards slowly – Start with just a few small leaves to allow the digestive system to adjust. Watch for soft stools as too much may cause diarrhea.

  • Limit to 1 cup per 5 lbs body weight – The total daily amount of vegetables (including collards) should be around 1 cup per 5 pounds of body weight.

  • Divide into multiple feedings – Don't feed too many collard greens at once. Give a few leaves at a time throughout the day.

  • Rotate with other veggies – For variety, swap out collard greens with other suitable veggies like kale, parsley, carrots, Bok choy, etc.

  • Skip if diarrhea develops – Stop feeding collards if they seem to be causing runny stool until the guts recover.

  • Restrict if bladder sludge occurs – Reduce oxalate-containing foods like collards if your rabbit has a history of bladder sludge.

Following these tips will allow your bunny to safely reap the nutritional perks of collard greens without risk of gastrointestinal upset. Pay attention to your individual rabbit's response.

Can Rabbits Eat Cooked Collard Greens?

Yes, it is perfectly fine and even beneficial to feed your rabbit cooked collard greens in moderation. Here's why:

  • Cooking softens cellulose – Heat breaks down tough cell walls, making nutrients more accessible. This helps with digestibility.

  • Inactivates harmful bacteria – Light cooking kills any potentially pathogenic bacteria like E. coli that may be present.

  • Retains nutrients – Quick cooking methods like steaming retain most of the vitamins, minerals, and antioxidants.

  • Removes some oxalates – Cooking may degrade a portion of the oxalic acid content.

  • Enhances palatability – Rabbits tend to relish the flavor of cooked collards over raw.

Steaming, blanching, or sautéing collard greens for 3-5 minutes is ideal. Make sure not to overcook them into mush. Allow the collards to cool to room temp before serving to your rabbit. Introduce cooked collards gradually and discontinue if any stomach issues arise. Overall, properly cooked collard greens are a nutritious addition to a rabbit's diet.

Can Rabbits Drink Collard Greens Juice?

Feeding collard green juice to rabbits is not recommended. Here are a few reasons why:

  • Concentrates oxalates – Juicing extracts the liquid while leaving oxalic acid compounds behind, increasing their proportion.

  • Alters nutrient balance – Important nutrients like protein and fiber are depleted during juicing. The resulting juice has an unbalanced nutritional ratio.

  • High in natural sugars – Juicing collards releases sugars but removes beneficial fiber that would normally slow sugar absorption. This could cause blood sugar spikes.

  • Encourages overconsumption – The sweet taste and lack of fiber in collard juice means rabbits may drink too much too quickly.

  • Digestive issues – The high volume of oxalates and sugars in collard juice poses a risk of intestinal upset in rabbits. Diarrhea or gas could occur.

  • Increased bladder sludge risk – With higher oxalate content, thickened urine or bladder sludge problems are more likely over time.

For these reasons, whole or lightly cooked collard greens are healthier options. If offering juiced veggies, use produce low in oxalates like carrots or celery instead of collard greens. Always dilute juices and limit to a few tablespoons at a time.

Do Rabbits Like Collard Greens?

Most rabbits seem to enjoy munching on fresh collard greens, especially when introduced to them at a young age. Here are some reasons why collards make a great treat:

  • Crunchy texture – Rabbits like to sink their teeth into the thick, fibrous leaves. The crispness satisfies their natural chewing urge.

  • Bright green color – The attractive green hue draws rabbits towards this veggie. Vibrant colors signifying plant vitality appeal to their foraging instincts.

  • Mild flavor – While bitter to some humans, most rabbits seem to accept and even relish the mild, somewhat sweet taste of collard leaves.

  • Moist and juicy – The high water content and succulent nature of collard greens is appealing for a rabbit's moisture needs.

  • Familiar scent – Rabbits have a strong sense of smell and may recognize collards as similar to other cabbage-family veggies they enjoy.

  • Cooling effect – Collards provide a cooling crunch that can be especially welcomed in hot weather.

Of course, every rabbit has unique preferences. Monitor your own rabbit's interest level when first offering collard greens. Most will eagerly gobble them up. For picky eaters, try rubbing the leaves with a flavor they enjoy or mixing small pieces into their salad. With time, collard greens often become a beloved component of a rabbit's diet.


Collard greens are a nutritious leafy green that, when fed properly, make an excellent addition to a pet rabbit's diet. Moderate amounts of fresh or cooked collard greens can provide vitamins, minerals, antioxidants, fiber and moisture. Pay attention to your individual bunny's response, and avoid overfeeding to prevent digestive upset. By following sound nutritional guidelines, collard greens can be a beneficial treat that rabbits hop to the chance to eat!
