Well, he's still itching his ears today! They don't look inflamed. Also, the rest of him is starting to shed. Hopefully it's just itchy fur coming out that makes him scratch! He also worried me yesterday in that when I let him out of his cage, he went and lay down behind the aquarium for about two or three hours. Normally he's going crazy running around when he first comes out and after 5 or 6 hours of that he lies down. I even pulled him out from behind the aquarium and held him for a bit but he went back. After a couple hours of lazing though, he got his hypers on and was running around and investigating my suitcase (he actually kind of climbed up it! It's one of those ones with shelves) and chowing down on food and treats. I guess he was just tired when I took him out! I agree though, he must be plotting to try and make me stay home! I really hope it isn't anything...
Good idea to tell the pet sitter about his forum! I wrote down every single phone number I could possibly be reached at as well as the phone number, address and hours of the vet and emergency vets. My instructions are about 4 pages long. All he has to do is make sure they are alive and have food and water, but I sure went into detail!
