What should a 4‑week‑old rat be fed? - in detail
A rat that is four weeks old is in the weaning stage and requires a diet that supplies high levels of protein, fat, calcium, and essential vitamins while remaining easily digestible.
Commercial weanling diets are the cornerstone of nutrition at this age. Choose a reputable brand that offers a “weanling” or “juvenile” formulation; these products typically contain 20–22 % protein, 8–10 % fat, and added calcium and vitamin D. Provide the block or pellets in a clean feeder, allowing the animal to eat ad libitum. Replace uneaten food daily to prevent spoilage.
Supplementary items can broaden the diet and encourage natural foraging behavior. Offer the following in small, measured amounts, refreshed each day:
- Soft fruits: banana (¼ cm slice), apple (peeled, ¼ cm cube), pear (peeled, ¼ cm cube)
- Vegetables: steamed carrot (¼ cm cube), broccoli floret (tiny piece), cucumber (¼ cm slice)
- Protein sources: cooked egg white (½ teaspoon), boiled chicken breast (finely shredded, ½ teaspoon), low‑fat plain yogurt (¼ teaspoon)
- Whole‑grain treats: small piece of whole‑grain bread or oatmeal (¼ teaspoon)
All fresh foods must be washed, peeled when necessary, and free of pesticides. Introduce each item individually and observe for digestive upset before adding another.
Feeding frequency should be three to four times per day. Divide the total daily allotment of commercial diet (approximately 5–7 grams for a typical weanling) into equal portions, and supplement with the listed foods in the same intervals. Monitor body condition; a healthy rat maintains a smooth, rounded abdomen and a glossy coat.
Fresh water must be available at all times in a bottle with a stainless‑steel spout. Change the water daily and clean the bottle to prevent bacterial growth. Regularly inspect the rat for signs of dehydration, such as sunken eyes or skin tenting, and adjust fluid intake accordingly.
