What should you do if rats don’t get along? - in detail

When pet rats exhibit aggression, immediate intervention prevents injury and reduces stress.

First, isolate the individuals involved. Place each rat in a separate cage with food, water, and bedding identical to the original environment. This prevents further fights while allowing observation of behavior and health.

Second, assess physical condition. Check for wounds, bite marks, or signs of illness such as nasal discharge or lethargy. Treat injuries with appropriate veterinary care; address any underlying disease that could provoke hostility.

Third, evaluate environmental factors. Overcrowding, limited resources, or lack of enrichment often trigger disputes. Ensure each cage provides ample space—minimum 0.5 sq ft per rat—and multiple feeding stations, water bottles, and hiding places. Rotate toys and introduce tunnels, chew blocks, and climbing structures to stimulate natural activity.

Fourth, consider re‑socialization. After a quarantine period of at least one week, re‑introduce the rats gradually:

  1. Place cages side by side with a solid barrier; allow visual and scent contact for several days.
  2. Swap bedding between cages to mix odors and reduce territorial marking.
  3. Conduct short, supervised sessions in a neutral enclosure—preferably a clean playpen—monitoring interactions closely.
  4. If aggression recurs, repeat isolation and extend the gradual exposure phase.

Fifth, monitor hierarchy development. Dominance is natural; occasional mild chases are normal, but persistent biting or severe fighting indicates incompatibility. In such cases, permanent separation may be necessary to safeguard welfare.

Finally, maintain routine health checks and consistent handling. Regular veterinary examinations, balanced nutrition, and daily interaction reduce stress and promote harmonious relationships among rats.
