When you notice your cat or dog’s eyes looking red and swollen, tearing up, or when they begin rubbing at them with their paws, conjunctivitis is one of the most common causes. This condition not only causes clear discomfort and pain—often accompanied by eyelid spasms or scratching—but may also stem from deeper underlying issues. So, if your pet shows these symptoms, be sure to take them to the vet to identify the true cause. Only by treating the root problem can you effectively resolve the irritation, prevent chronic recurrence, and protect pet eye health in long term!
