How is a rat washed? - in detail
Cleaning a laboratory rat requires restraint, appropriate tools, and attention to hygiene. Begin by assembling a clean work surface, a shallow container of warm water (approximately 37 °C), mild laboratory‑grade soap, soft brushes, disposable towels, and a disinfectant for the area afterward. Wear disposable gloves and, if required, protective eyewear.
- Restraint – Hold the animal gently but securely using a trained technique such as the tail‑hold method or a specialized restraining tube. Avoid excessive pressure that could cause injury.
- Pre‑wash inspection – Examine the fur and skin for wounds, parasites, or debris. Document any abnormalities before proceeding.
- Wet the coat – Submerge the rat briefly in the warm water, allowing the fur to become saturated. Keep the head above water to prevent inhalation.
- Apply cleanser – Dispense a small amount of mild soap onto a soft brush or fingertip. Massage the solution through the fur, moving from the neck toward the tail. Focus on areas prone to accumulation, such as the ventral surface and hindquarters.
- Rinse – Transfer the animal to a second container of clean warm water. Rinse thoroughly until no soap residue remains; visual inspection of the water can confirm clarity.
- Dry – Pat the rat with disposable paper towels, removing excess moisture. Follow with a brief exposure to a low‑temperature airflow dryer (≤30 °C) if required by protocol, ensuring the animal remains calm.
- Post‑wash care – Return the rat to its cage, provide fresh bedding, and monitor for signs of stress or hypothermia. Clean and disinfect all equipment according to institutional guidelines.
Throughout the process maintain a calm environment, minimize handling time, and adhere to ethical standards for animal welfare.
