The excellent photos reveal conjunctivitis usually caused by feline herpesvirus (FHV-1). Thankfully, it usually goes into remission unaided within 1-3 weeks. The bacteria Mycoplasma and Chlamydophila can be found in conjunction with FHV-1 or as sole infecting agents but they, too, should go into remission unaided in that time frame. In the case in which my patient doesn't improve within the initial 10 days from the onset of symptoms, the antibiotic of choice - doxycycline - should be prescribed by Sushi's attending vet to address those bacteria. Over the counter (not in all states) Terramycin* ophthalmic ointment is a good choice for bacterial conjunctivitis should this arise. It's reasonable to assume that it may have and so dosing is a 1/4" ribbon of ointment on to the cornea (clear window of the eye) thrice daily for a minimum of 10 consecutive days. If you don't see improvement within that period of time, please note that FHV-1 can cause such damage to the cornea (clear window) of the eye that the cornea can rupture often leading to loss of the eye.

Antibiotics don't address viruses such as FHV-1 but her vet can prescribe the antiviral drug famciclovir if the vet thinks that a serious case of FHV-1 is brewing.

As long as she continues to eat, drink, and act normally in spite of the clinical signs of upper respiratory infection, and infected eyes don't worsen, Sushi doesn't need to be attended to by her vet. Please respond with further questions or concerns if you wish.


If you can't find Terramycin ophthalmic ointment over the counter and a vet's attention isn't possible here's the next best choice: Discontinue its use if you see worsening rather than improvement.
