So I have heard some of the home remedies if the RI is minor, and was wondering if I could get some clarification on them.

1) Drop humidity and maintain high ambient temp in well ventilated enclosure - has anyone tried this with success? If so, what constant ambient temp did you keep it at (90?), what kind of enclosure did you keep it in, and how did you drop the humidity (remove the water bowl?).
2) Nebulizer with water/f10 disinfectant mix - has anyone tried this with success? How many days did this treatment take? How long was the treatment each day (20-40 mins?)
3) Any other suggestions that have worked for you (with details)?

Thanks in advance for your help/advice. Obviously if it doesn't improve or gets worse, off to the vet!
