Many people assume that rex rabbits can eat the same diet as other rabbit breeds, but their unique coat and slightly slower metabolism mean they need careful attention to fiber and protein balance. Our editorial team has gathered the facts so you can feed your rex rabbit correctly.
Rex rabbits have a distinct genetic makeup that affects their digestive efficiency, so their diet must prioritize unlimited grass hay and controlled portions of leafy greens to prevent obesity and dental issues.
The Foundation: Unlimited Grass Hay
For rex rabbits, hay is the most important part of their diet. Timothy hay is ideal, but orchard grass or meadow hay also work well. Rex rabbits have a slightly stockier build and can be prone to weight gain, so hay provides the necessary fiber to keep their digestive system moving and to wear down their continuously growing teeth.
Offer a constant supply of fresh hay in a rack or feeder. Avoid alfalfa hay for adult rex rabbits because it is too high in calcium and protein, which can lead to bladder sludge and obesity. Young rex rabbits under 7 months can have alfalfa mixed with grass hay for extra growth support.
Fresh Vegetables and Leafy Greens
Rex rabbits thrive on a variety of dark leafy greens. Introduce new vegetables one at a time to monitor for digestive upset. Good options include romaine lettuce, kale, cilantro, parsley, and dandelion greens. Avoid iceberg lettuce and spinach in large amounts due to low nutrition or high oxalates.
A general guideline is about 1 cup of greens per 2 pounds of body weight daily, split into two feedings. Rex rabbits often enjoy vegetables more than some other breeds, but moderation is key to prevent soft stools.
Pellets: Choose Wisely and Limit
Rex rabbits need a high-fiber, low-protein pellet to match their metabolism. Look for pellets with at least 18% fiber and no more than 14% protein. Avoid pellets with seeds, nuts, or colorful pieces, as these can cause selective feeding and obesity.
For an adult rex rabbit, feed about 1/8 to 1/4 cup of pellets per 5 pounds of body weight daily. Rex rabbits are prone to becoming overweight if overfed pellets, so measure carefully and reduce if your rabbit starts gaining weight.
Treats and Foraging
Rex rabbits love treats, but they should be reserved for occasional use. Safe options include small pieces of apple, banana, carrot, or berries, all without seeds or pits. Offer no more than a teaspoon-sized portion once or twice a week.
Foraging is excellent for mental stimulation. Provide fresh herbs like basil or mint, or safe branches from apple or willow trees. This mimics natural behavior and helps keep your rex rabbit active and engaged.
Hydration and Health Monitoring
Fresh, clean water must always be available. Use a heavy ceramic bowl or a sipper bottle, and change water daily. Rex rabbits may drink more than some breeds due to their dense coat, especially in warm weather.
Monitor your rex rabbit’s eating habits and droppings. Changes in appetite or small, misshapen fecal pellets can indicate dental or digestive issues. Regular vet checkups are important to catch problems early.
