Early signs may include a small bump, redness, or scab at the scratch/bite site, followed days to weeks later by tender, enlarged lymph nodes nearby. Mild fever, fatigue, and headache can occur. Some people mainly feel generalized malaise or sore throat. These early signs are not specific; recent cat exposure plus characteristic lymph node swelling increases diagnostic suspicion. Evaluation is recommended if symptoms worsen, eye symptoms appear, or fever persists.
