What should I do if a rat's eye is tearing? - in detail
If a pet rat exhibits excessive tearing, begin by isolating the animal to prevent further irritation and to allow close observation. Examine the affected eye for signs of redness, swelling, discharge color, or foreign material. Use a bright, but not harsh, light source and gently retract the eyelid with a clean fingertip or a soft cotton swab.
Identify potential causes:
- Injury – scratches, punctures, or blunt trauma.
- Infection – bacterial, viral, or fungal agents producing purulent or cloudy discharge.
- Dental issues – overgrown incisors can press against the orbital cavity, causing irritation.
- Allergens – dust, bedding, or food particles that may provoke a conjunctival reaction.
- Systemic disease – conditions such as respiratory infections can manifest with ocular symptoms.
Once a likely cause is suspected, take the following actions:
- Clean the eye – moisten a sterile gauze or cotton pad with warm saline (0.9 % NaCl) and gently wipe away discharge. Do not apply ointments or drops without veterinary guidance.
- Prevent self‑trauma – place the rat in a calm, low‑stress environment and limit contact with other cage mates that might provoke fighting.
- Seek veterinary assessment – schedule an appointment promptly. A veterinarian will perform a thorough ocular exam, possibly including fluorescein staining to detect corneal ulcers, and may prescribe topical antibiotics, anti‑inflammatory drops, or systemic medication depending on the diagnosis.
- Address underlying issues – if dental overgrowth is identified, arrange for trimming. Replace bedding with dust‑free material, and ensure the diet is balanced to support overall health.
Monitor the rat closely for changes in tear volume, discharge appearance, and behavior. Improvement should be evident within 24–48 hours of appropriate treatment; lack of progress or worsening signs warrants immediate veterinary re‑evaluation. Maintaining a clean cage, providing adequate nutrition, and regular health checks reduce the likelihood of recurrent ocular problems.
