I've only had my BP for about 5 days, and I took him out the cage today to clean some things, and I noticed him "whistling" when he breathed. Unfortunately, it might be RI, but because I've never seen it before, I'm not 100% positive. When I first got him, I was having trouble heating the cool side (it was at 77 for the first 2 days, but now it's at 84), but I'm thinking the damage is already done. I've read a lot of posts on here about RI and going to the vet, but I would just like to hear your thoughts on the matter. My main problem is that I'm leaving to go back to school this friday, so if something needs to be done, I have to do it ASAP. Your thoughts would be greatly appreciated.

ps. He never leaves his warm side hide...which is between 91 and 93...do you think he's trying to keep his temps up in order to fight the disease?
