What should be done if a rat bites another rat? - briefly
Isolate the bitten rat, examine the wound, clean it with an appropriate antiseptic, and arrange prompt veterinary evaluation; also observe both animals for infection signs and provide supportive care as needed.
What should be done if a rat bites another rat? - in detail
When a rat attacks and wounds a conspecific, immediate separation of the individuals is required to prevent further injury and to allow safe handling of the victim.
First, place the injured animal in a clean, quiet enclosure with soft bedding. Observe the wound for size, depth, and signs of bleeding. If bleeding is profuse, apply gentle pressure with sterile gauze until it slows or stops.
Next, disinfect the area. Use a dilute solution of chlorhexidine or povidone‑iodine; avoid harsh antiseptics that could damage delicate tissue. Rinse the wound with sterile saline, then dry it with a clean gauze pad.
After cleaning, assess the need for professional veterinary care. Indications include:
- Lacerations larger than 2 mm or penetrating deeper than the skin
- Signs of infection: swelling, pus, foul odor, or heat
- Persistent bleeding despite pressure
- Behavioral changes such as lethargy, loss of appetite, or abnormal grooming
If any of these criteria are met, transport the rat to a veterinarian experienced with rodents. The clinician may prescribe antibiotics (e.g., enrofloxacin) to prevent bacterial complications, analgesics for pain management, and possibly sutures for major wounds.
Monitor the rat for at least 48 hours. Check the wound daily for redness, discharge, or reopening. Maintain a temperature‑controlled environment (22–25 °C) and provide easy access to food and water to support recovery. Reduce stress by limiting handling and eliminating sources of aggression, such as overcrowding or territorial disputes.
Prevent future incidents by:
- Housing rats in groups no larger than three to five individuals, depending on cage size
- Providing ample enrichment and hiding places to reduce competition
- Ensuring all animals are healthy, as illness can increase aggression
- Conducting regular health checks to identify and isolate aggressive individuals promptly
Document the incident, including date, observed behavior, wound description, and treatment administered. This record assists in evaluating patterns of aggression and informs adjustments to husbandry practices.
