How Long Do Cat Eye Infections Last?
Cat eye infections are more common than many pet owners realize—and while they often look alarming, most resolve quickly with proper care. The duration depends on the cause, severity, and how soon treatment begins. Understanding what to expect can ease your worries and help your feline friend recover faster, with minimal discomfort.
Common Causes of Feline Eye Infections
Before determining how long an eye infection will last, it’s crucial to understand what’s causing it. Several factors can trigger ocular issues in cats—some mild, others requiring immediate veterinary attention.
Feline Herpesvirus (FHV-1):
This highly contagious virus is a leading cause of upper respiratory infections and conjunctivitis in cats, often leading to recurring eye issues.Bacterial Infections:
Bacteria like Chlamydia felis or Mycoplasma commonly cause redness, discharge, and swelling, especially in kittens or multi-cat households.Foreign Bodies or Trauma:
A scratch from another cat, plant debris, or dust can irritate the eye and lead to secondary infection if not cleaned properly.Allergies:
Environmental allergens such as pollen, smoke, or cleaning products may cause watery, itchy eyes that mimic infection symptoms.Blocked Tear Ducts:
Some cats, especially flat-faced breeds like Persians, have narrow tear ducts that clog easily, causing chronic tearing and secondary inflammation.
Identifying the root cause is essential—not only for effective treatment but also to prevent recurrence. Never assume all eye issues are the same; what looks like a simple irritation could be a sign of something more serious.
Typical Duration of Cat Eye Infections
The length of time a cat’s eye infection lasts varies widely based on its origin and treatment. However, general timelines offer helpful guidance for concerned pet owners.
Viral Infections (e.g., Feline Herpes):
Symptoms usually last 7 to 14 days, though some cats experience flare-ups throughout life during periods of stress.Bacterial Infections:
With appropriate antibiotic ointment or drops, improvement often begins within 48–72 hours, and full resolution typically occurs in 5 to 10 days.Mild Irritation or Allergies:
These may clear up in 2 to 5 days once the allergen is removed and supportive care (like saline rinses) is provided.Corneal Ulcers or Trauma:
Healing can take 7 to 21 days, depending on severity, and often requires prescription medication and follow-up exams.Chronic Conditions (e.g., entropion, dry eye):
These aren’t true infections but cause persistent symptoms that may need lifelong management rather than “curing.”
While many infections resolve within one to two weeks, never wait more than 24–48 hours to seek veterinary advice if you notice squinting, cloudiness, or yellow/green discharge. Early intervention prevents permanent damage.

| Infection Type | Expected Duration |
|---|---|
| Viral (e.g., Feline Herpes) | 7–14 days (may recur) |
| Bacterial | 5–10 days with treatment |
| Allergic/Irritant | 2–5 days after trigger removal |
| Corneal Ulcer or Injury | 7–21 days (vet-monitored) |
| Chronic Ocular Conditions | Ongoing management required |
Signs Your Cat Has an Eye Infection
Cats can’t tell us when they’re uncomfortable—but they show clear physical and behavioral cues. Recognizing these early can shorten recovery time and prevent complications.
Excessive Tearing or Discharge:
Clear fluid may indicate mild irritation, but yellow, green, or thick discharge often signals infection.Redness or Swelling:
Inflamed eyelids or bloodshot eyes are classic signs of conjunctivitis or trauma.Squinting or Holding Eye Closed:
This protective behavior suggests pain or light sensitivity—never ignore it.Cloudiness or Change in Eye Appearance:
A hazy cornea or visible third eyelid can indicate ulceration or uveitis.Rubbing or Pawing at the Eye:
While occasional grooming is normal, repeated pawing suggests discomfort or foreign material.
If you notice any of these symptoms, isolate your cat from other pets (in case it’s contagious) and contact your vet promptly. Early diagnosis drastically improves outcomes.
Home Care Tips While Waiting for the Vet
While professional care is essential, gentle home support can ease your cat’s discomfort during the first 24 hours before an appointment.
Use Sterile Saline Rinse:
Flush the eye gently with preservative-free saline to remove debris or discharge—never use tap water or human eye drops.Keep the Area Clean:
Wipe away crusts with a soft, damp cloth using separate sections for each eye to avoid cross-contamination.Prevent Further Irritation:
Remove air fresheners, smoke, or dusty litter that could worsen symptoms during recovery.Avoid Over-the-Counter Meds:
Many human or dog eye products are toxic to cats. Never apply anything without veterinary approval.Monitor for Worsening Signs:
Watch for lethargy, loss of appetite, or both eyes becoming affected—these warrant emergency care.
These steps support healing but do not replace veterinary treatment. Think of them as first aid—not a cure.
When to See a Veterinarian Immediately
Not all eye issues wait for business hours. Some require urgent attention to save vision or prevent systemic illness.
Both Eyes Are Affected:
This often indicates a viral or systemic infection needing prompt antivirals or antibiotics.Visible Injury or Penetration:
Any sign of trauma—like a cut, scratch, or protruding eye—needs emergency evaluation.Cloudy or Blue-Tinted Cornea:
This suggests corneal ulceration, which can perforate within hours if untreated.Swollen or Protruding Third Eyelid:
Known as “cherry eye” in dogs, in cats it often signals pain, dehydration, or serious infection.Your Cat Is Lethargic or Not Eating:
Systemic illness (like feline herpes flare-up) can cause eye symptoms alongside fever or appetite loss.
When in doubt, call your vet. Most clinics offer same-day appointments for ocular emergencies.
Preventing Future Eye Infections in Cats
Once your cat recovers, take proactive steps to reduce recurrence—especially if they’ve had herpes or chronic issues.
Keep Vaccinations Up to Date:
The FVRCP vaccine helps prevent severe herpes and calicivirus outbreaks.Reduce Stress in the Home:
Stress triggers herpes flare-ups; use Feliway diffusers, consistent routines, and quiet spaces.Maintain Clean Litter and Bedding:
Bacteria thrive in dirty environments—clean food bowls, litter boxes, and sleeping areas weekly.Avoid Multi-Cat Overcrowding:
In shelters or catteries, infections spread rapidly; ensure adequate space and hygiene.Schedule Regular Wellness Checks:
Annual exams catch early signs of dry eye, entropion, or other predisposing conditions.
Prevention isn’t just about cleanliness—it’s about creating a stable, low-stress environment where your cat’s immune system stays strong.
When Scratching Becomes a Red Flag
While scratching is entirely normal, certain patterns may signal underlying medical or behavioral issues that need professional attention. Knowing what to watch for can make the difference between routine care and urgent intervention.
Bleeding or Swollen Paws:
Persistent scratching that causes wounds, redness, or swelling may indicate infection, allergy, or injury.Sudden Increase in Scratching Frequency:
A dramatic change in behavior—especially if paired with vocalizing or restlessness—can point to pain or anxiety.Scratching Only One Side of the Body:
This asymmetry often suggests localized discomfort, such as an ear mite infestation or skin lesion.Hair Loss Around Scratched Areas:
Excessive licking or scratching leading to bald patches may be a sign of dermatitis, fleas, or stress-related overgrooming.Avoidance of Favorite Scratching Spots:
If your cat stops using their post altogether and seems lethargic, it could reflect joint pain or illness.
If any of these signs appear, consult your veterinarian promptly. What looks like behavioral scratching could actually be your cat’s way of coping with hidden discomfort. Early diagnosis ensures your feline returns to healthy, happy scratching—on their terms, not out of distress.
Frequently Asked Questions About Cat Eye Infections
How long does it take for a cat’s eye infection to clear up?
Most bacterial infections improve within 3 days and resolve in 5–10 days with treatment. Viral cases may last 1–2 weeks.
Can cat eye infections go away on their own?
Mild irritation might, but true infections rarely resolve without intervention—and delaying care risks permanent damage.
Are cat eye infections contagious to other cats?
Yes—especially those caused by feline herpesvirus or *Chlamydia*. Isolate infected cats until symptoms fully resolve.
Can humans catch eye infections from cats?
Extremely rare. Most feline eye pathogens are species-specific and do not infect people.
What should I do if my kitten has goopy eyes?
Seek veterinary care immediately. Kittens dehydrate quickly and are vulnerable to blindness from untreated infections.
