We have what seems to be a perfectly healthy young cat-----about 8 months old ---a stray we've had for about 2 months. EXCEPT----several times a day she "blows her nose" or sort of sneezes---sending a large mucous slug in inappropriate places. I CAN'T have this inside the house! Is she just prone to sinus troubles or might this be a low grade infection that can be cured? As I said "I can't have this in my house" and I anguish over the possible need to make her a barn cat or have her put to sleep. Any ideas?
