Okay, I realize it's a URI, I AM taking him to the vet in the morning, or calling so I can hopefully get into the vet asap. I just wanted to know if in the mean time besides increasing his heat, which I've already done, should I decrease the humidity or decrease it to help him further.
The person that told me to increase humidity had experience with RI's in Blood's, the person that told me to decrease had experience with corns and boas. So I was unsure what the protocol for ball's was and I'm still getting conflicting info, LOL!

I guess the general consensus is to decrease the humidity for ball's, and just do what I've been doing until I get him into the vet tomorrow. Even though it "may" clear up on it's own without antibiotics, I'm going to have him checked out since he went through such an awful ordeal. He may have a heavier than normal parasite load because of all the stress so a checkup certainly won't hurt.

Thanks for the advice and if anyone can offer more input on the dry heat vs. moist heat, I'd love to hear it. Thanks!
