Is Fresh Grass Safe for Rabbits to Eat?

Fresh grass from the yard can be a healthy part of a rabbit's diet when fed in moderation. Rabbits are herbivores, meaning they naturally eat grasses, vegetables, fruits, and other plant materials. In the wild, rabbits graze on grasses and weeds as a major component of their diet. However, not all types of yard grass are safe for pet rabbits.

Grass provides rabbits with roughage that is important for healthy digestion and nutrient absorption. The fiber in grass helps promote intestinal motility to prevent issues like gastrointestinal stasis. Fresh grass also provides moisture to keep rabbits hydrated. When rabbits eat, their food undergoes fermentation in the intestines, which produces beneficial fats and proteins for energy. The greens provide vitamins like vitamin A, C, K, folate, and more.

However, yard grass may have been treated with pesticides, herbicides, or fertilizers that can be toxic to rabbits if ingested. These chemicals can cause gastrointestinal upset, neurological issues, organ damage, and even death in severe cases. Always verify the grass has not been chemically treated before offering it to pet rabbits.

Grass that is soiled with dog, cat or wild animal feces can expose rabbits to parasites and illnesses. Do not let pet rabbits graze in yards or parks frequented by other animals. Stick to grass you grow in your own organic garden without chemicals.

Even organic grass should be introduced slowly to allow the rabbit's digestive system to adjust. Rotate grass with the rabbit's usual hay diet for a few days to avoid any stomach upset from the change. Grass has lower fiber and higher moisture and protein than hay, so unlimited grass can potentially cause diarrhea.

The safest options are grass hays like timothy, oat hay, Bermuda grass hay, or meadow hay. You can buy these pre-packaged for rabbits, or grow your own organic grass hay. Introduce fresh lawn clippings gradually alongside the regular grass hay diet. Monitor the rabbit's stool and reduce grass intake if diarrhea occurs.

Can Rabbits Eat Grass Instead of Hay?

Rabbits should not eat grass instead of hay as their main dietary component. Hay is crucial to provide the indigestible fiber rabbits need for healthy gut function. Grass is higher in nutrients and moisture, and too much can cause digestive upset.

Hay helps grind down rabbit teeth that continually grow. The abrasive nature of hay allows rabbits to wear down their teeth naturally. Grass does not provide the same abrasive quality to maintain dental health.

Compared to grass, hay is lower in calcium and protein. Excess calcium and protein can lead to painful bladder stones and kidney damage in rabbits. The optimal calcium content of a rabbit's diet should be around 1%, which grass exceeds.

Hay also contains more vitamins, minerals and antioxidants important for rabbit nutrition. Grass lacks some nutrients rabbits need in their daily diet. Feeding only grass could lead to nutritional deficiencies over time.

Lastly, hay provides mental stimulation and satisfaction for rabbits. Rabbits enjoy foraging for strands of hay, which prevents boredom and destructive behaviors. Grass does not provide the same enrichment effect.

The House Rabbit Society recommends a daily diet of unlimited grass hay, limited grass or greens, limited fruit and vegetables, and a small amount of fortified pellets. Hay should make up at least 75% of a rabbit's food intake to promote good digestion and dental health.

Grass can be fed as a supplemental treat in small quantities, but should never completely replace hay. If your rabbit refuses to eat hay, consult an exotic vet to identify and treat the underlying issue.

Can Rabbits Have Too Much Grass?

Yes, rabbits can have too much grass. Even though grass is a natural part of the rabbit diet, it does need to be fed in limited quantities. Excess grass can lead to gastrointestinal and urinary tract issues in rabbits.

Grass contains higher levels of moisture, protein and calcium compared to hay. The moisture and protein levels are close to those found in high-quality rabbit pellets. Feeding unlimited pellets and grass can throw off the ideal balance of nutrients in the rabbit's diet.

Specifically, excess calcium from grass can lead to painful bladder sludge and stones. The calcium binds with oxalates from other foods to form solid crystals and stones in the urinary tract. A rabbit's urinary system is designed to process small amounts of calcium, not high levels.

Too much grass can also cause loose cecotropes (night feces rabbits reingest) and diarrhea. The higher moisture and sugar content in grass make it more digestible compared to coarse hay. Rabbits' digestive systems are adapted for hay, not fresh greens.

Diarrhea causes electrolyte imbalances and dehydration, and forces the intestinal tract to empty before nutrients can be absorbed. Over time, chronic diarrhea can lead to weight loss and gastrointestinal disorders.

A good rule of thumb is to feed no more than 1 packed cup of grass per 2 lbs body weight per day. Split this into multiple small meals rather than one large portion. Observe the rabbit's appetite, stool and urine output when introducing grass. Reduce the amount if soft stool occurs.

Make sure grass is just a small component of the diet alongside unlimited hay, a limited amount of leafy greens, and a limited amount of pellets and fruits. This balance will keep your rabbit's digestive system healthy.

Can Pet Rabbits Eat Lawn Clippings?

Rabbits can eat small amounts of fresh lawn clippings in moderation. However, lawn clippings may pose some health risks that are important to consider before feeding them.

Lawn clippings can provide a source of grass without rabbits having to graze outside. If you maintain your lawn organically without chemicals, fresh clippings can be a nutritious occasional treat. Introduce them slowly in small quantities to make sure they do not cause digestive upset.

However, there are some factors that make lawn clippings less ideal than hay or bagged organic grasses. Grass clippings made with a standard lawnmower can be contaminated by gas, oil, or antifreeze from the mower itself. Ingesting these toxic substances could make a rabbit very ill.

Lawn clippings also tend to be damp and compacted, which can promote mold growth during storage. This mold could irritate a rabbit's respiratory tract. Dry the clippings fully in the sun before feeding.

Compacted lawn clippings may also pose a choking hazard compared to loose hay. Damp grass can compact into a ball in the mouth making swallowing difficult. Monitor the rabbit's consumption and watch for difficulty chewing or swallowing.

Lastly, excess lawn clippings can throw off the ideal calcium to phosphorus ratio in the diet. Both nutrients are needed, but in specific proportions for bone health.

Overall, it is safer to grow and harvest your own organic grass for rabbits. But if you do feed lawn clippings, offer them in limited amounts alongside the regular hay diet. Make sure they are mold-free, chemical-free and fed under supervision.

Can Rabbits Eat Grass from the Lawnmower?

It's best to avoid feeding rabbits grass collected from the lawnmower discharge chute. Grass cut by a lawnmower poses some health risks to rabbits and is not as safe as other grass options.

One main concern is the potential for contamination by the lawnmower itself. As the blades grind the grass, any chemicals, dirt or debris on them can be transferred to the grass clippings.

Gas and oil leaks are common on lawnmowers. These toxic substances could coat the grass clippings as they pass through the mower. Even small amounts of gas or oil can be dangerous if ingested by a rabbit.

Chemicals used on the lawn like pesticides, weed killers and fertilizers also have the potential to end up in the grass clippings. Rabbits grazing on chemically treated lawns are at risk as well.

The clippings that shoot out of a mower tend to be compact and moist. Wet grass can quickly mold, especially in the warm temperatures inside a running mower. Moldy grass can irritate a rabbit's digestive and respiratory tract.

The damp, compacted texture of machine-cut grass also poses a choking risk compared to loose hay preferred by rabbits. It may be difficult for them to properly chew and swallow the wad of clippings.

While trace amounts may not cause illness, it is not worth the risk of chronic exposure to lawn mower contaminants. Rabbits also should not graze near running mowers where fumes are present.

For the healthiest grass diet, grow your own organic grass, let it dry out, then harvest it by hand. You can also buy bags of dried grass hay labeled safe for rabbits. Avoid feeding grass clippings from an operating lawnmower.

Would a Pet Rabbit Eat Pesticides?

In most cases, a pet rabbit would avoid eating grass sprayed with harmful pesticides. However, accidental ingestion is still possible depending on the type of pesticide used.

Rabbits rely heavily on their senses of taste and smell to detect toxins in potential foods. Strong bitter or unnatural odors typically cause rabbits to avoid eating a plant or leaf.

Many common pesticides have very bitter tastes and strong odors that rabbits instinctively reject by smell or after one nibble. For example, organophosphate and carbamate insecticides are extremely bitter with a chemical smell that deters ingestion.

However, rabbits' natural deterrents do not work for some newer pesticides. Some taste and smell relatively benign despite being highly toxic. Neonicotinoids like imidacloprid are odorless and not bitter to rabbits.

Without taste/smell cues identifying these pesticides as toxic, rabbits may eat treated grass and fall ill.

Another factor is pesticide persistence in the environment and how thoroughly it coats the plants. Highly persistent chemicals are more likely to unintentionally transfer during grooming or gradual ingestion.

Weather conditions also play a role – rain can dilute pesticide concentrations, while heat and UV light break some chemicals down over time. Proper application technique reduces excess runoff onto unintended plants.

If you must use pesticides in your yard, never let pet rabbits out to graze for at least 2 weeks after treatment. Always keep untreated grass hay available so rabbits are not tempted by treated grass.

The best option is to grow organic grass and herbs that do not require pesticide use. Hand pick any invading bugs rather than resort to chemical pest control in rabbit areas.

Be aware that your neighbors likely use chemical pest and weed control in their lawns. Do not allow pet rabbits to graze in community grassy areas where exposure is beyond your control.

Can a Rabbit Eat Weeds and Plants from the Yard?

Pet rabbits should not freely graze on weeds and random plants in the yard, as many common species are toxic. However, some specific weeds and plants are safe in moderation if correctly identified.

Toxic yard invaders like bindweed, buttercups, chickenweed, foxglove, knotweed, nightshade, plantain and ragweed can cause illness or death in rabbits. Typical lawn and garden flowers like azaleas, chrysanthemums, daffodils, marigolds and tulips are also unsafe.

Some weeds like dandelions and clover are suitable for rabbits. Dandelion leaves and clover blossoms can be fed in limited amounts. Make sure the yard is free of chemical sprays before harvesting.

Edible wild herbs rabbits can eat include chickweed, mallow, plantago, wild violet leaves and flowers. Introduce new weeds slowly to watch for any digestion issues. Always cross-reference with a list of rabbit-safe plants first.

The House Rabbit Society recommends planting a "salad bar" garden of bunny-friendly herbs and plants. Choose a pesticide-free corner of your yard. Grow herbs like basil, dill, fennel, mint and oregano which are safe and tasty for rabbits.

Research any unfamiliar plants or weeds thoroughly before feeding them to rabbits. Consider working with an herbologist or wildlife expert to positively identify safe vs toxic species. When in doubt, do not allow your rabbit to eat unknown vegetation.

With proper plant identification and supervision, feeding limited edible weeds and herbs can provide variety and enrichment. Just be cautious, as your yard likely contains many toxic species that could seriously harm pet rabbits.


Rabbits can eat some grass from the yard in moderation, but pet owners need to be very selective about the source. Grass can provide nutrients, but also poses risks if contaminated by chemicals, dirt, feces or mold. Harvest grass clippings yourself from an organic lawn or grass you grow specifically for your rabbit. Introduce new grasses slowly and monitor for any digestive issues. Limit total grass intake to no more than 1 cup per 2 lbs body weight per day to prevent health issues. Avoid lawn clippings from the mower discharge as they may contain contaminants. Do not allow pet rabbits to freely graze on grass treated with pesticides or unknown weeds. With caution and proper identification of safe species, grass and select weeds from the yard can be a healthy supplemental addition to your rabbit's diet when fed in small amounts.
