What does a white rat eat? - briefly
White rats thrive on a balanced diet of high‑quality rodent pellets supplemented with fresh vegetables (e.g., carrots, broccoli), fruits (e.g., apple, banana), and occasional protein sources such as cooked eggs or mealworms. They also tolerate small amounts of grains, nuts, and commercial treats, provided the overall intake remains nutritionally balanced.
What does a white rat eat? - in detail
White rats require a balanced diet that supplies protein, fat, carbohydrates, fiber, vitamins, and minerals. Commercial rodent blocks or pellets form the nutritional core; they are formulated to deliver approximately 14‑20 % protein, 5‑7 % fat, and essential micronutrients. A daily portion of 1‑2 grams per 100 g body weight is adequate for adult animals.
Fresh vegetables augment the diet with fiber and vitamins. Suitable options include:
- Leafy greens: romaine lettuce, kale, spinach (offered in small amounts, washed thoroughly)
- Root vegetables: carrot slices, beet tops, broccoli florets
- Squash and cucumber pieces
Fruits may be given as occasional treats due to high sugar content. Recommended selections are apple (seedless), banana, berries, and melon, limited to no more than 10 % of total intake.
Protein supplements support growth, lactation, and recovery. Acceptable sources are:
- Cooked egg white (no seasoning)
- Small pieces of lean chicken or turkey breast
- Mealworms or dried insects (moderate quantity)
Water must be continuously available in a clean bottle; rats consume 20‑30 ml per 100 g body weight each day.
Foods to avoid because of toxicity or digestive risk include:
- Citrus fruits and juices
- Chocolate, caffeine, alcohol
- Raw potatoes, raw beans, avocado
- Sticky or sugary human snacks
Feeding schedules should be consistent. Provide fresh food each morning, remove uneaten perishables after 12 hours to prevent spoilage. Juvenile rats (under 8 weeks) need higher protein (up to 22 %) and more frequent feeding, while seniors benefit from reduced fat and added joint-support supplements such as glucosamine.
Monitoring body condition, coat quality, and fecal consistency helps assess dietary adequacy. Adjust portions or ingredients promptly if weight loss, obesity, or digestive disturbances appear.
