It is the area right before his nostrils, on the top of his head, over his mouth. I can't get a good picture of it, he is not happy and not cooperating.

He (3 year old IJ) shed on the 12th and a day or so before that I noticed he looked 'puffy', but I figured it was from the impending shed, he does get very dry and flaky. I fed him a medium rat on the 13th, he hid for a few days and looked fine after. I offered him dinner on the 25th and he refused, he never refuses, and thought his snout looked a tad swollen again. Yesterday it was noticeably more swollen and today it is very swollen.

I called the vet and he is going in tomorrow morning but I was hoping you guys could perhaps take a stab at what might be going on. I noticed nothing out of the ordinary going on in his mouth (got a good look as he yawned). He has not been yawning more than usual, no popping, no wheezing, no discharge.

I trust my vet but this is the first real, true health concern I have had with him. Any insight or ideas would be appreciated.
