What should you do if a rat bites another rat? - in detail
When a rodent injures a companion, immediate action is required to protect both animals and prevent infection.
First, separate the aggressor from the victim. Use a clean container or a separate cage to avoid further contact. Observe the injured rat for bleeding, puncture wounds, or signs of distress. Apply gentle pressure with a sterile gauze pad to control any bleeding; if bleeding persists after several minutes, seek emergency veterinary care.
Next, clean the wound. Rinse with warm saline solution (0.9% sodium chloride) to remove debris. Pat dry with sterile gauze. Do not apply human antiseptics such as hydrogen peroxide or alcohol, as they can damage delicate tissue. If the bite is deep or the skin is torn, a veterinarian should perform suturing and prescribe appropriate antibiotics.
After initial treatment, quarantine the affected rat for at least two weeks. During quarantine, monitor temperature, appetite, and behavior daily. Record any changes, including swelling, discharge, or lethargy, and report them promptly to a professional.
Simultaneously, assess the aggressor. Check for injuries that could cause pain‑induced aggression. Ensure the animal is healthy, vaccinated (if applicable), and free of parasites. If the aggressor shows repeated hostile behavior, consider behavioral modification, environmental enrichment, or permanent separation to avoid future incidents.
Preventive measures include:
- Providing ample space per animal (minimum 0.5 sq ft per rat) to reduce territorial disputes.
- Supplying multiple feeding stations, water bottles, and nesting sites to eliminate competition.
- Maintaining a stable, low‑stress environment with consistent lighting, temperature (18‑24 °C), and minimal handling stress.
- Introducing new rats gradually, using a neutral enclosure and scent swapping before cohabitation.
Finally, document the incident, treatment steps, and outcomes. This record assists veterinary professionals in diagnosing potential infections such as Streptobacillus moniliformis or other rodent‑borne pathogens.
Prompt separation, proper wound care, quarantine, and environmental management constitute the comprehensive response to a bite incident between rats.
