An adult Lilac Rabbit's diet should be centered on unlimited grass hay, which provides the long-strand fiber that keeps the gastrointestinal tract functioning properly and wears the continuously growing teeth at a healthy rate. Timothy hay is the most widely recommended variety, but orchard grass, meadow hay, botanical hay blends, and oat hay all serve the same purpose and can be rotated to maintain the rabbit's interest. Hay should constitute at least 80 percent of the daily diet by volume, and a Lilac Rabbit that is eating well will consume a body-sized pile of hay each day.
Pellets transition from a growth-supporting staple during the juvenile stage to a measured supplement in adulthood. The standard adult ration is approximately one-quarter cup of high-fiber, plain pellets per five to six pounds of body weight per day. Choose a pellet with at least 18 percent crude fiber, moderate protein around 12 to 14 percent, and no added sugars, seeds, or dried fruit pieces. Pellets that include colorful additives encourage selective feeding and contribute unnecessary calories. Overfeeding pellets is one of the most common nutritional errors in adult rabbit care and frequently leads to obesity, reduced hay consumption, and downstream dental problems.
Fresh vegetables form the third pillar of the adult Lilac Rabbit's diet. Offer a varied daily salad comprising approximately one packed cup of leafy greens per two pounds of body weight. Suitable options include romaine lettuce, red and green leaf lettuce, cilantro, parsley, dill, basil, endive, escarole, and dandelion greens. Introduce new vegetables one at a time and monitor droppings for changes over 48 hours. Limit high-oxalate greens such as spinach and Swiss chard to occasional use, and avoid iceberg lettuce, which offers minimal nutrition and excess water content that can loosen stools.
Fruits should be treated strictly as occasional treats, offered in quantities no larger than one to two tablespoons per day. A thin slice of apple, a few blueberries, or a small piece of banana provides a rewarding treat for training or bonding without introducing significant sugar into the diet. The Lilac Rabbit's compact frame means that even modest caloric excesses accumulate quickly, so restraint with treats is essential for maintaining healthy body condition throughout the adult years.
Fresh water must be available at all times, and consumption should be monitored as an indirect health indicator. A sudden increase in water intake may signal kidney issues or diabetes, while a marked decrease can precede gastrointestinal stasis. Provide water in a heavy ceramic crock, a gravity-fed bottle, or both, and clean the vessel daily to prevent bacterial growth.
