Cat with 6+ months of clear nasal drainage.

[DrSher 0]

I need some help here. Our cat has nasal drainage that does not seem to go away. Her vet treated her for infection at first, but it did not do much.

She is otherwise a 13 year old healthy Russian cat and they are resilient like nothing else.

Does anyone have any instant magical fix here? I am leaning towards thinking it is allergies, but not sure how to treat a cat for it.

There is still lots of time to learn it..
