My JoJo is 8 mo old now. He was 4 mo old when I rescued him! He has had this URI since we got him. He has been to two vets and on antibiotics several times. Nothing works. He is on Lysine and Lactoferrin. The vets suggest I get him a Nasal Endoscopy,suggesting maybe he has polyps in his sinus! The cat specialist want $1900 to $ 2400.00 for this test!!! Where do they think seniors living on Fixed income can come up with this kind of money! So I am wondering if anybody has any home remedies for URI (sneezing/wheezing/mucus).....
