What should be given a rat for constipation? - briefly
Administer a mild osmotic laxative such as lactulose or a low‑dose polyethylene glycol solution, dosing ≈ 0.5–1 mL per 100 g body weight. Ensure adequate hydration and provide a fiber‑rich diet (e.g., fresh vegetables) to promote normal stool passage.
What should be given a rat for constipation? - in detail
Constipation in laboratory or pet rats requires prompt intervention to restore normal bowel function and prevent complications.
Adequate hydration is the primary measure. Provide fresh water ad libitum and consider adding a small amount of electrolyte solution (for example, 0.9 % saline) to the drinking supply for 24–48 hours.
Dietary adjustments should include high‑fiber foods. Offer chopped raw carrots, cooked broccoli, or a measured portion of oat bran (approximately 1 g per 100 g body weight) daily. Ensure the fiber source is introduced gradually to avoid gas accumulation.
If hydration and fiber fail to produce stools within 12–24 hours, a gentle laxative may be administered. Recommended options:
- Lactulose – oral solution, 0.5 mL per 100 g body weight, given once daily.
- Polyethylene glycol (PEG 3350) – powder reconstituted in water, dose 10 mg per 100 g body weight, administered orally.
- Mineral oil – 0.2 mL per 100 g body weight, given once, may be repeated after 12 hours if needed.
Pharmacological agents should be used under veterinary supervision. For severe or refractory cases, a short course of a pro‑kinetic drug such as metoclopramide (0.2 mg/kg, subcutaneous) may be considered, but only after exclusion of underlying disease.
Monitoring parameters:
- Stool frequency and consistency, recorded at least twice daily.
- Body weight, measured daily to detect dehydration or weight loss.
- Activity level and grooming behavior, as reduced activity may indicate discomfort.
If no improvement occurs within 48 hours, or if the rat exhibits signs of abdominal distension, lethargy, or vomiting, immediate veterinary evaluation is required to rule out obstruction, neoplasia, or metabolic disorders.
Preventive strategies include maintaining a balanced diet with 5–7 % crude fiber, providing continuous access to water, and avoiding excessive high‑fat or low‑fiber treats. Regular health checks help identify early gastrointestinal disturbances.
