HIssing Sound

[Sarin]

He did just have a bad shed maybe 2 weeks ago. Also, he has hissed at me and it sounds similar, but its very short and seems like it is every time he exhales. I will keep a good eye on him the next day or so. Got the vets number on speed dial just incase.

It's most likely just stuck shed in the nostrils then. Still keep an eye on him and if he starts wheezing and bubbling then it's definitely an RI. But don't get too worried about it yet.
