The only home treatment a cat owner can provide for a cat with an eye infection is to use a damp cotton ball to wipe away the discharge, according to WebMD. A veterinarian must determine the cause of the infection and tailor treatment accordingly, states PetEducation.com.
The cause of an eye infection in a cat may be bacterial or fungal, or an allergy may be responsible, explains PetEducation.com. For bacterial or fungal infections, the vet may prescribe bactericidal or fungicidal ointments or eye drops. He may also prescribe oral antibiotics. If the eye infection is due to an allergy, the vet typically prescribes anti-inflammatory preparations that contain hydrocortisone.
