Back in February, our soon to be 16 yr old Norton, had a terrible URI. I used the vaporizor, but I also mixed up GOLD SEAL Elixir(available at health food shops). I took several dops of the exilir and put it into about 30cc's of normal saline. And with the help of an army, Barry and I put 2 drops in each nostril several times a day. The gold seal helps in relieving the congestion and reduces the inflamation(sp) of the mucos membranes. Maybe that will help your boy!!! Sending prayers along, too.....

PS: If you can get a copy of Anitra Frazier"s the " New Natural Cat " this info is in there!!!
