What should you feed domestic rats and in what amount? - briefly
Domestic rats need a balanced diet of high‑quality commercial rat pellets as the staple, complemented by modest portions of fresh vegetables, fruit, and occasional protein treats; offer roughly 15–20 g of pellets per 100 g of body weight each day, split into two feedings. Supplementary foods should not exceed 10 % of the total intake.
What should you feed domestic rats and in what amount? - in detail
Domestic rats require a balanced diet that supplies protein, fat, fiber, vitamins, and minerals. A high‑quality laboratory‑grade or commercial rat block should form the foundation; these pellets contain 18–20 % protein and essential nutrients. Offer the block continuously, allowing the animal to eat as needed, but replace any uneaten portion daily to maintain freshness.
Fresh vegetables provide fiber and micronutrients. Suitable options include carrot slices, broccoli florets, spinach leaves, kale, and cucumber. Provide 1–2 grams of vegetables per 100 g of body weight each day. Rotate varieties to prevent nutrient gaps and avoid feeding large amounts of oxalate‑rich greens such as beet leaves.
Fruit can be offered as an occasional supplement because of high sugar content. Small pieces of apple, banana, berries, or melon should not exceed 5 % of the total daily intake. For a 200‑gram adult rat, this translates to roughly 1 gram of fruit per day.
Protein sources beyond the pellet blend enhance growth and reproductive health. Cooked egg white, plain cooked chicken, or low‑fat plain yogurt may be given in 0.5‑gram portions per feeding, up to three times weekly. Avoid processed meats, seasonings, and raw eggs.
Treats should be limited to 2–3 percent of the diet. Commercial rat treats, nuts, or small pieces of cheese can be used for enrichment, but monitor caloric contribution to prevent obesity.
Water must be available at all times in a clean bottle with a stainless‑steel spout. Replace water daily and check for leakage.
Feeding schedule for adults: continuous access to pellets, fresh vegetables once or twice daily, fruit and protein treats on a limited schedule, and treats sparingly. Juvenile rats (under 8 weeks) require 15–20 grams of pellet mixture per day, supplemented with higher‑protein foods such as boiled egg yolk (0.5 gram) and finely chopped vegetables (2–3 grams). Adjust quantities proportionally for larger or pregnant individuals, increasing overall intake by 10–20 percent.
