My cat bullets had conjunctivitis off and on for about 3 months, tried erythromycin and it went away but came back, got some more of the ointment and also doxycycline in pill form, but it's not going away. Has anyone ever delt with this before? At its worst, swelling of inner eyelid was so bad you couldn't see his eye. It's much better now but still has the inner eyelid poking out a bit with discharge all the time. Been to the vet times not sure what to do, a specialist is very expensive and I don't have the money right now. Doxycycline is almost gone and have half a tube of erythromycin left but it just won't go away. Anyone have some insight?
