Hi. I'm online and happy to answer your question today.
I am human eye doctor and don't usually give advice on cats, but as a long time cat owner I can tell you what has worked for me in the past.
If you use your index finger to gently massage the corner of her affected eye (the side against her nose) multiple times a day this may help to open the blocked tear duct. As long as there is no evidence of infection you don't have to use the aureomycin ointment.
Continue to keep the area clean. If things don't resolve in a month or so, or if it seems to become infected, then you should see your vet.
does this make sense to you?
And, now, the obligatory word from our sponsors: :o)
