Proper nutrition is absolutely fundamental to Standard Chinchilla health and longevity, with the foundation of their diet being unlimited, high-quality grass hay available at all times without exception. Timothy hay is the gold standard for adult rabbits, though orchard grass, meadow hay, brome, oat hay, and other grass hays provide excellent alternatives and beneficial variety. Alfalfa hay is too rich in protein and calcium for adult rabbits over 7 months old and should only be fed to growing kits during their rapid growth phase. Hay is the single most important component of rabbit diet and must never be considered optional or supplementary.
Hay serves multiple absolutely essential functions for Standard Chinchillas and all rabbit breeds. It provides the long-strand fiber necessary for healthy digestive function, keeping the gastrointestinal system moving properly through peristalsis and preventing life-threatening GI stasis. The constant, prolonged chewing required to break down fibrous hay naturally wears down continuously growing teeth at the proper rate, preventing painful dental disease, malocclusion, and overgrowth that can lead to starvation. Hay also keeps rabbits mentally occupied through natural grazing behaviors that can occupy hours daily, reducing boredom and providing important environmental enrichment. Standard Chinchillas should consume approximately a bundle of hay equal to their body size every single day.
Hay quality matters tremendously for encouraging adequate consumption and providing nutritional benefits. Fresh, green, sweet-smelling hay with no signs of mold, excessive dust, yellowing, browning, or discoloration is essential. Reject hay that smells musty or moldy, appears brown or yellow indicating age, feels damp or wet, or contains visible mold growth. Store hay properly in a cool, dry, well-ventilated location protected from moisture and pests to preserve quality and prevent deterioration. Many rabbits are quite particular about hay quality and freshness, refusing hay that's old, dusty, or improperly stored. Finding hay brands and types your individual rabbit enjoys is important for ensuring adequate consumption.
Offer hay in multiple ways throughout the living space to encourage constant grazing throughout the day and night. Use hay racks or feeders to keep hay clean, dry, and off the floor. Scatter loose hay around the enclosure for natural foraging behaviors. Stuff hay into cardboard tubes, paper bags, or treat balls for enrichment. Place generous amounts of hay directly in or immediately beside the litter box, taking advantage of rabbits' natural tendency to eat while eliminating. Refresh hay multiple times daily—at least morning and evening—to maintain appeal and freshness. Never allow hay supplies to run completely out, as even brief periods of 12-24 hours without hay can trigger dangerous digestive slowdowns that quickly become life-threatening.
High-quality rabbit pellets should be fed in controlled, carefully measured portions to provide concentrated balanced nutrition without causing obesity. Adult Standard Chinchillas weighing 5-7.5 pounds typically need 1/4 to 1/3 cup of pellets daily maximum, divided into morning and evening feedings at consistent times. The exact amount varies based on individual size, activity level, metabolism, and body condition. Choose plain timothy-based pellets with at least 18-20% fiber content, low calcium levels under 1%, moderate protein around 12-14%, and minimal fillers or additives. Avoid pellets with added seeds, dried fruit, colored pieces, or other unnecessary ingredients that add calories, sugar, and fat without nutritional benefit.
Young Standard Chinchillas under 7 months old need unlimited alfalfa-based pellets to support rapid growth and development during their critical growing phase. Begin transitioning to timothy-based adult pellets around 7 months of age, gradually mixing increasing amounts of timothy pellets with decreasing amounts of alfalfa pellets over 2-3 weeks. This gradual transition prevents digestive upset while allowing the young rabbit's system to adjust to adult diet composition. By one year of age, Standard Chinchillas should be fully transitioned to carefully measured adult portions based on their mature size and activity level.
Fresh vegetables are an important component of a healthy, balanced Standard Chinchilla diet and should be introduced gradually starting around 12 weeks of age. Adult Standard Chinchillas should receive 2-3 cups of fresh leafy greens and vegetables daily, adjusted based on individual size and tolerance. Excellent vegetable choices include romaine lettuce (not iceberg), green and red leaf lettuce, butter lettuce, cilantro, parsley, basil, mint, dill, arugula, watercress, dandelion greens, carrot tops, bok choy, endive, escarole, radicchio, and various lettuces excluding iceberg. Avoid iceberg lettuce entirely, which has minimal nutritional value and high water content that can cause diarrhea.
Provide variety by offering 3-5 different types of greens each day, rotating between available options throughout the week. This rotation ensures balanced nutrition, prevents boredom, and exposes rabbits to various beneficial nutrients. Introduce each new vegetable one at a time in small amounts, monitoring carefully for digestive upset including soft stools or diarrhea over 24 hours before making it a regular diet component. Some vegetables like broccoli, cauliflower, cabbage, and Brussels sprouts can cause significant gas if introduced too quickly or fed in excess, so offer these cruciferous vegetables sparingly, if at all. Vegetables like bell peppers, carrots in moderation due to sugar content, celery, and herbs can be included in smaller amounts as part of the vegetable rotation.
Always wash all vegetables thoroughly under running water to remove pesticides, dirt, bacteria, and other contaminants. Pat dry or use a salad spinner. Feed vegetables at room temperature rather than straight from the refrigerator to prevent digestive discomfort and bloating. Discard any uneaten vegetables after several hours to prevent spoilage, bacterial growth, and contamination. Monitor which vegetables your Standard Chinchilla prefers while ensuring they eat adequate variety rather than only favorite items. Some rabbits become picky eaters if consistently allowed to refuse less-preferred foods, so maintain variety even if they show preferences.
Fruits should be treated as occasional treats only, offered no more than 1-2 times weekly in very small quantities—approximately 1-2 tablespoons maximum for medium-sized rabbits like Standard Chinchillas. Suitable fruits include apple slices without seeds (which contain cyanide), banana, strawberries, blueberries, raspberries, blackberries, pear, melon, and small amounts of pineapple. Fruits are extremely high in natural sugars that contribute significantly to obesity, dental problems, digestive upset, and unhealthy gut bacteria imbalances if overfed. Use tiny fruit pieces as occasional training rewards or special treats rather than regular dietary components. Many healthy rabbits never receive fruit and thrive perfectly well.
Certain foods are toxic to rabbits and must never be fed under any circumstances. Dangerous foods include avocado (extremely toxic causing heart damage), rhubarb (toxic causing kidney damage), chocolate (toxic), onions, garlic, leeks, chives, potato plants and raw potatoes, tomato leaves and stems, iceberg lettuce (causes severe diarrhea), nuts, seeds, crackers, bread, cookies, cereal, candy, corn, beans and legumes, raw or dried beans, and any processed human foods. Even seemingly healthy foods can be problematic—for example, while carrot tops and greens are excellent, carrot roots should be limited to small amounts due to high sugar content. Research any new food thoroughly using reputable sources before offering it to your rabbit.
Fresh, clean water must be available at all times in either heavy ceramic bowls that can't be easily tipped or sipper bottles with ball bearings. Many rabbits prefer drinking from bowls as it allows more natural drinking posture and typically encourages higher water consumption, which is beneficial for kidney and urinary health. However, bottles prevent water contamination from bedding, droppings, or food debris. Offering both options simultaneously ensures adequate hydration regardless of individual preference. Check water sources multiple times daily—minimum twice but ideally more often—refreshing with clean water as needed. Clean water containers daily with hot water and mild dish soap to prevent bacterial growth, biofilm development, and algae formation.
Feeding schedules should be remarkably consistent to reduce stress and help rabbits feel secure in their routine. Offer measured pellet portions in morning and evening feedings at approximately the same times daily. Provide fresh vegetables in the evening feeding after the rabbit has had opportunity to eat hay and pellets. Keep unlimited hay available constantly throughout the entire day and night, refreshing multiple times daily to maintain appeal and freshness. Young Standard Chinchillas under 7 months need unlimited pellets and alfalfa hay to support growth, gradually transitioning to carefully measured adult portions as they mature over several months.
Monitor body condition regularly by gently feeling for the spine and ribs—bones should be easily felt without prominent protrusion, but they shouldn't be buried under thick fat layers. The compact body type should feel solid and substantial but not overweight. Adjust food portions based primarily on actual body condition rather than arbitrary measurements, though also consider individual needs, activity level, age, and metabolism. Standard Chinchillas getting substantial daily exercise may need slightly more food than completely sedentary individuals, though base adjustments primarily on body condition assessment. Regular weighing weekly helps track trends—sudden weight loss or unexpected gain warrants immediate veterinary attention.
Obesity is extremely dangerous for rabbits, dramatically increasing risks of numerous serious health problems including fatty liver disease, arthritis, sore hocks, difficulty grooming leading to hygiene issues, and significantly reduced lifespan. Conversely, unexpected weight loss often indicates serious underlying illness requiring prompt diagnosis and treatment. Maintaining ideal weight through appropriate portions and adequate exercise is crucial for Standard Chinchilla health and longevity.
Monitoring fecal output is a crucial daily aspect of rabbit care and health assessment. Healthy droppings should be round, firm, relatively uniform in size approximately pea-sized, and produced in extremely large quantities—rabbits typically produce 200-300 individual pellets daily. Droppings that are small, irregularly shaped, connected by hair or fur, soft, mushy, or dramatically reduced in number indicate potential serious health problems. Any changes in appetite, water consumption, or fecal production quantity or quality require immediate emergency veterinary attention, as these are often the earliest warning signs of life-threatening conditions like GI stasis that require prompt aggressive treatment. Cecotropes—soft, clustered, shiny droppings produced overnight that rabbits eat directly from their bodies—are completely normal, essential for nutrition, and should not be confused with diarrhea. Proper feeding combined with vigilant daily monitoring ensures your Standard Chinchilla maintains optimal health and beautiful condition.
