• Clarity and brightness
• Equal pupil size in normal light
• Minimal, clear tear discharge
• Pink, healthy conjunctival tissue
• No cloudiness, haziness, or visible blood vessels
• No squinting, rubbing, or excessive blinking

Eye Color Variations

Common Colors:

• Green (most common)

Routine Eye Care: Prevention is Key

Daily Observation

Incorporate a quick eye check into your daily petting routine. Look for:

• Any discharge (color, consistency, amount)
• Redness or swelling
• Behavioral changes (increased rubbing, squinting, light sensitivity)
• Symmetry between both eyes

Gentle Cleaning Protocol

When to Clean:

• Mild tear staining (reddish-brown streaks)
• "Sleep" or crust in the corners
• Occasional clear discharge
• Flat-faced breeds require daily cleaning.

Supplies:

• Soft, lint-free cloth or sterile cotton ball
• Warm water or veterinarian-approved eye wash solution
• Separate cloth for each eye to prevent cross-contamination
• Treats for positive reinforcement

Step-by-Step Cleaning:

1. Wash your hands thoroughly.
2. Dampen the cloth with warm water or eye wash.
3. Gently wipe from the inner corner outward, using a single stroke.
4. Use a clean section of the cloth for each wipe and each eye.
5. Never touch the eyeball directly or apply pressure.
6. Gently pat the area dry.
7. Praise and reward your cat to create a positive association.

Special Care for Flat-Faced (Brachycephalic) Breeds

Breeds Needing Extra Attention: Persian, Himalayan, Exotic Shorthair, some Scottish Folds and British Shorthairs.

Why Extra Care is Crucial:

• Shallow eye sockets and protruding eyes increase exposure.
• Tears often pool and cause staining.
• Malformed tear ducts are common, leading to epiphora (excessive tearing).
• Higher risk of corneal ulcers and infections.

Daily Routine:

• Clean eyes at least twice daily (morning and evening).
• Keep facial folds clean and dry to prevent dermatitis.
• Be vigilant for signs of redness or irritation.
• Schedule regular veterinary check-ups.

Common Feline Eye Conditions

Conjunctivitis (Pink Eye)

Description: Inflammation of the conjunctiva (the pink membrane lining the eyelids).

Symptoms:

• Redness and swelling
• Squinting or holding the eye closed
• Discharge (clear, yellow, or green)
• Pawing at the face

Causes: Viral (feline herpesvirus), bacterial infections, allergies, foreign bodies, trauma.

Treatment: Requires veterinary diagnosis. Treatment may include antibiotic/antiviral drops and addressing the underlying cause. Can be contagious.

Corneal Ulcers

Description: A scratch or open sore on the clear cornea.

Symptoms:

• Intense squinting and pain
• Excessive tearing
• Cloudy spot on the cornea
• Sensitivity to light

Causes: Trauma (scratches, foreign bodies), dry eye, infection.

Treatment: A veterinary emergency. Diagnosed with fluorescein stain. Treatment includes antibiotic drops, pain medication, and often an Elizabethan collar. Deep ulcers may require surgery.

Cataracts

Description: Clouding of the eye's lens, leading to vision impairment.

Symptoms:

• A cloudy, bluish, or white appearance in the pupil
• Clumsiness, bumping into objects
• Hesitation in unfamiliar places

Causes: Aging, diabetes mellitus, genetics, trauma, or inflammation.

Treatment: Surgical removal is an option. Managing underlying conditions (like diabetes) is crucial. Cats often adapt remarkably well to gradual vision loss.

Glaucoma

Description: A painful condition caused by increased pressure inside the eye.

Symptoms:

• A bulging or enlarged eye
• Cloudy cornea
• A fixed, dilated pupil
• Redness and visible pain

Causes: Can be primary (genetic) or secondary to other eye diseases like uveitis or tumors.

Treatment: A true emergency. Requires immediate vet care to reduce pressure with medications or surgery to prevent permanent blindness.

Uveitis

Description: Inflammation of the eye's middle layer (uvea), including the iris.

Symptoms: Similar to conjunctivitis but with a small, irregular pupil, severe cloudiness, and often more pain.

Causes: Often a sign of serious systemic disease (e.g., infection, immune disorder, cancer, toxoplasmosis).

Treatment: Requires urgent veterinary care to treat the inflammation and identify the underlying cause.

Tear Duct Issues & "Cherry Eye"

Epiphora (Excessive Tearing): Constant wetness and staining, often due to blocked nasolacrimal ducts, especially in flat-faced breeds.

Third Eyelid Prolapse (Cherry Eye): The gland of the third eyelid protrudes, appearing as a red mass in the corner of the eye. Requires surgical correction.

Recognizing Eye Emergencies

Seek Immediate Veterinary Attention For:

• Sudden blindness or obvious vision loss
• Eye bulging (proptosis)
• Severe trauma or penetrating injury
• Chemical exposure
• Blood inside the eye (hyphema)
• Sudden, severe cloudiness
• Signs of intense pain: Vocalizing, hiding, aggression, refusing to eat.

Preventive Care & Maintenance

Environmental Safety

• Cat-proof your home: Secure cleaning chemicals, cover sharp furniture corners, use window screens.
• Supervise interactions with other pets to prevent fight-related injuries.
• Maintain good air quality: Avoid smoke, use pet-safe cleaners, and consider an air purifier.

Nutrition for Optimal Eye Health

A balanced, high-quality commercial cat food provides essential nutrients:

• Taurine: An absolute essential; deficiency causes central retinal degeneration and blindness.
• Vitamin A: Critical for corneal health.
• Antioxidants (Vitamins C & E, Lutein): Help protect against oxidative damage and cataracts.
• Omega-3 Fatty Acids: Support retinal and tear film health.

Regular Veterinary Check-ups

Annual wellness exams should include an ophthalmic check. Senior cats (7+) benefit from semi-annual visits. Your vet may perform:

• Schirmer Tear Test: Measures tear production.
• Fluorescein Stain: Detects corneal ulcers.
• Tonometry: Measures intraocular pressure (glaucoma screening).

Breed-Specific Eye Concerns

Genetic Testing: Responsible breeders test for hereditary conditions like PRA. Ask for documentation if adopting a purebred kitten.

Home Care & Administration of Medication

How to Give Eye Drops or Ointment

1. Prepare: Wash hands, have medication and treats ready.
2. Position: Gently hold your cat's head, tilting the chin up.
3. Administer: Use one finger to pull down the lower eyelid, creating a pouch. Apply the drop/ointment into this pouch, not directly onto the eyeball.
4. Finish: Allow your cat to blink, distributing the medication. Reward generously.

Pro Tip: Wrapping your cat in a towel (a "purrito") can help restrain them safely. Stay calm and patient.

Caring for a Blind Cat

Cats adapt brilliantly to vision loss. Enhance their world by:

• Keeping your furniture layout consistent.
• Using scent markers (like a dab of vanilla on furniture corners).
• Talking to them before touching to avoid startling.
• Providing auditory and scent-based toys.
• Ensuring they are indoor-only for safety.

Frequently Asked Questions (FAQs)

Q: Why does my cat have tear stains? A: Common in flat-faced breeds due to anatomy. It can also signal irritation, infection, or blocked ducts. Daily cleaning helps; see a vet if it worsens.

Q: Can I use human eye drops on my cat? A: Never. Many human medications (especially those with steroids) are toxic to cats. Use only veterinarian-prescribed products.

Q: Why are my cat's pupils two different sizes? A: Unequal pupils (anisocoria) is a serious sign that can indicate neurological issues, glaucoma, or trauma. Seek veterinary care immediately.

Q: Do cats get cataracts from diabetes? A: Yes. Diabetes mellitus is a leading cause of cataracts in cats. Proper diabetic management is crucial.

Q: How well do cats see? A: Cats have excellent night vision and motion detection but see fewer colors than humans (primarily blues and yellows). Their vision is about 20/100 to 20/200.
