When my RB Pepper had a very bad URI, I had him sit in front of a vaporizer. I put him in his cat carrier and put the vaporizer close to him so the steam would go toward his nose. My vet also said that I could use "Little Noses" decongestant nose drops. These are the pediatic nose drops and you can buy this in any drug store. You only put one drop in each nostril up to 2 times a day I think. I sure hope that Boo feels better soon and that Bettie stays well too. Prayers and positive thoughts are on the way. Please take care.
