Conjunctivitis is one of the most common eye conditions in cats, caused by viral, bacterial, and allergic factors, causing discomfort and potentially long-term eye damage if untreated.
Eye discomfort from conjunctivitis is a significant but often underappreciated welfare concern in cats. Ocular pain and irritation cause behavioral changes including hiding, reduced activity, and reluctance to be handled. Cats with chronic herpes-related conjunctivitis experience recurring flares throughout their lives that temporarily impair vision and cause discomfort. Stress management is a welfare intervention for these cats, as psychological stress is a primary trigger for FHV-1 recurrence. Shelter cats are particularly susceptible to conjunctivitis outbreaks, and the condition is a leading cause of eye problems in feral cat populations. Prompt treatment not only relieves suffering but prevents the progressive corneal damage that can lead to blindness in severe or neglected cases.
