How do cats' eyes get infected? - briefly
Cats' eyes can become infected due to bacteria, viruses, fungi, or foreign particles entering the eye, often exacerbated by injuries, allergies, or underlying health conditions.
How do cats' eyes get infected? - in detail
Cats' eyes can become infected through various mechanisms, often involving bacteria, viruses, fungi, or parasites. One of the most common causes is bacterial infection, which can occur when harmful bacteria, such as Chlamydia felis or Mycoplasma, enter the eye. This can happen due to scratches, foreign objects, or poor hygiene. Viral infections are another significant cause, with feline herpesvirus (FHV-1) being a frequent culprit. This virus is highly contagious and can spread through direct contact with an infected cat or contaminated surfaces. Fungal infections, though less common, can also affect cats, particularly in environments with high humidity or exposure to soil contaminated with fungi like Aspergillus or Cryptococcus. Parasites, such as Thelazia (eye worms), can infect a cat’s eyes when they come into contact with infected insects or contaminated water. Additionally, physical trauma, such as scratches or injuries, can create openings for pathogens to invade the eye, leading to infections. Environmental factors, like dust, smoke, or allergens, can irritate the eyes and make them more susceptible to infections. Poor immune function, whether due to stress, age, or underlying health conditions, can also increase a cat’s vulnerability to eye infections. Symptoms of an eye infection in cats may include redness, swelling, discharge, squinting, or excessive tearing. Prompt veterinary attention is crucial to diagnose the cause and provide appropriate treatment, which may include antibiotics, antivirals, antifungals, or supportive care to alleviate discomfort and prevent complications.
