Any Veternarians on line or connected or long time cat owners with more vast experiences? My cat, Princess (16 yrs old and only 6 lbs) has a bit of a blocked tear duct. Minor tearing along her nose makes a dark marking which I have been rinsing with water. I have an ointment "VetropolycinHC" that I received before when this happended but I don't know if I should just go ahead and use it again. I have an appt to take her in next week but did not know if anyone had any interim advice to share. Another issue is that she has gotten intimidated by my other cat, Snowy, (6 yrs old and fat at 16 lbs) and Princess has taken to spending all of her time in the various closets if I am not holding her. She also eats very little. Is she shutting down? Thanks for any shared experiences or advice.
