I found this cat – not sure what’s wrong with its eyes, but it looks hungry

The photo you uploaded is blurry, so the cat’s exact condition cannot be determined. If the eyelid is swollen, consider conjunctival edema, eyelid dermatitis, irritants, injury, or infection.

First clean the eye gently with saline, then apply pet-specific anti-inflammatory eye drops and watch for improvement. If the symptoms do not improve or worsen, take the cat to a veterinary clinic for examination and treatment.
