He was sedated for the x rays but the vet did blood tests and skin samples to try and find out why his belly is so red and itchy. Apparently the tests are for dust mites, pollen and grass. The vet said if anything comes back positive they can do a vaccine injection. Thank god for pet insurance!
Please do keep us posted of the injections -- I am guessing these are to desensitize against the allergens? With an itchy boy, too, I am very interested.
