Why Did My Cat Start Excessive Nose Dripping Clear Fluid?
Sounds like a cold.... Keep an eye on her an if your worried....vet!!!
My cat's nose does the same thing when she wants affection from me. She's never been sick and as far as I know for her it is normal. Similar to how a dog will get slubbery when they are petted. I suggest you Natural home remedies through this you get more results about herbal remedies .
