My 12 yr. old neutered cat is bleeding from one nostral. I noticed it first when he sneezed. Could this just be from the dry air inside our home that he may not be used to? Or does it signify something more serious?

I would be worried about a grass seed or something stuck up your cats nose.

I had a scare earlier today where my dog was continuously sneezing, and we pulled a seed from her nose not long after.
