If you've noticed your cat's eye appearing red, you're likely concerned about their ocular health. Red eyes in cats can signal various conditions, from minor irritations to serious medical issues requiring immediate attention. Understanding the causes, symptoms, and appropriate treatments is crucial for maintaining your feline friend's eye health.
This comprehensive guide will help you identify potential causes of red eyes in cats, recognize when immediate veterinary care is needed, and learn about available treatment options. Let's explore everything you need to know about this common feline health concern.
Common Causes of Red Eyes in Cats
Red eyes in cats typically occur when blood vessels in the eye become enlarged, causing the white part (sclera) to appear pink or red. Several conditions can trigger this response:
Infections
Bacterial and viral infections are among the most common causes of red eyes in cats. Feline herpes virus and bacterial infections like Chlamydia felis frequently lead to conjunctivitis, causing redness, swelling, and discharge. These infections are particularly common in kittens and cats with weakened immune systems.
Allergies and Irritants
Environmental allergens, such as dust, pollen, or cleaning products, can trigger allergic reactions in cats' eyes. These reactions often cause redness accompanied by itching and watery discharge. Some cats may also develop sensitivities to certain grooming products or environmental changes.
Physical Trauma
Scratches, foreign objects, or direct injuries to the eye can cause immediate redness and inflammation. Even minor trauma requires prompt attention to prevent complications and ensure proper healing.

Beyond redness, watch for these additional signs that might indicate an eye problem:
