What to feed a water rat? - in detail

A water rat requires a balanced diet that mimics its natural foraging habits. Protein sources should dominate, supplemented with plant matter and occasional treats.

  • Animal protein:

    • Live or frozen insects (crickets, mealworms, waxworms) – 30–40 % of daily intake.
    • Small pieces of cooked fish or lean meat – 10–15 % of daily intake.
    • Commercial rodent pellets formulated for semi‑aquatic species – 20 % of daily intake.

  • Vegetable matter:

    • Fresh leafy greens (kale, romaine lettuce, spinach) – 15–20 % of daily intake.
    • Soft vegetables (cucumber, zucchini, carrots) – 5–10 % of daily intake.
    • Aquatic plants (duckweed, watercress) – optional supplement for enrichment.

  • Fruits and occasional supplements:

    • Small portions of berries, apple slices, or melon – no more than 5 % of total calories.
    • Calcium powder or vitamin D3 supplement applied to food twice a week, especially if indoor lighting is limited.

Water availability is critical; provide fresh, clean water at all times, preferably in a shallow dish that allows the animal to swim or soak.

Feeding schedule should consist of two to three meals per day, with quantities adjusted to maintain a stable body condition. Monitor weight and fecal consistency; excessive weight gain or soft stools indicate the need to modify protein levels or increase fiber.

Avoid toxic foods such as avocado, chocolate, onions, and any processed human snacks. Replace spoiled or moldy items immediately to prevent gastrointestinal distress.

Regularly rotate protein and vegetable varieties to prevent nutritional deficiencies and to stimulate natural foraging behavior. This comprehensive approach supports optimal health, growth, and longevity for a water rat.
