Isolate the rat, keep it in a calm, warm environment, and contact a veterinarian immediately for examination and treatment. Avoid administering any medication without professional guidance.

What should I do if a pet rat has a red eye? - in detail

If a rat’s eye appears reddened, begin with a visual inspection. Look for swelling, discharge, or a visible lesion. Note whether the redness is unilateral or affects both eyes, and record any accompanying signs such as sneezing, nasal discharge, lethargy, loss of appetite, or changes in grooming behavior.

Next, isolate the affected animal to prevent possible spread of infection. Provide a clean, quiet cage with fresh bedding, avoiding any drafts or direct sunlight that could exacerbate irritation. Ensure constant access to clean water and a balanced diet to support immune function.

Examine the eye more closely using a bright, non‑flashlight source. Gently retract the eyelid to assess the conjunctiva, cornea, and pupil. Look for:

  • Clear or mucoid discharge – suggests bacterial or viral conjunctivitis.
  • Ulcerated or cloudy cornea – indicates trauma, vitamin A deficiency, or severe infection.
  • Blood vessels engorged with a glossy surface – may be a mild inflammation or allergic response.

If the redness is mild, the animal is eating, and no discharge is present, monitor for 24‑48 hours while maintaining a clean environment. Apply a sterile saline rinse (0.9 % NaCl) to flush the eye once daily, using a dropper or a clean cotton ball. Do not use over‑the‑counter eye drops formulated for humans without veterinary guidance.

Should any of the following occur, seek professional veterinary care promptly:

  • Persistent or worsening redness after 24 hours.
  • Presence of discharge, especially if thick, yellow, or green.
  • Signs of pain such as squinting, pawing at the eye, or reluctance to eat.
  • Visible ulceration, corneal opacity, or pupil irregularities.

A veterinarian may perform a fluorescein stain test to detect corneal ulcers, culture the discharge to identify bacterial agents, and prescribe appropriate treatments. Common prescriptions include:

  • Topical ophthalmic antibiotics (e.g., enrofloxacin or trimethoprim‑sulfamethoxazole) applied 2–4 times daily.
  • Anti‑inflammatory eye drops or systemic non‑steroidal anti‑inflammatory drugs to reduce swelling.
  • Systemic antibiotics if a deeper infection is suspected.

Follow the prescribed dosing schedule precisely, completing the full course even if symptoms improve. Re‑evaluate the rat after treatment; normal tear production and clear corneas indicate recovery.

Preventive measures reduce recurrence:

  • Clean cages weekly, replace bedding regularly, and disinfect food dishes.
  • Provide a balanced diet rich in vitamin A (e.g., fortified pellets, occasional leafy greens).
  • Avoid exposing rats to drafts, smoke, or strong odors that can irritate the ocular surface.
  • Conduct routine health checks, watching for early signs of eye irritation.

Prompt identification, appropriate isolation, and veterinary intervention are essential to protect ocular health and overall welfare.
