Gina, I'm so glad to hear that Merlin will be okay. What a dreadful scare for you and your family, especially Merlin himself. I had a question and was wondering if you or someone else had an answer. You said your vet told you that the allergy was very rare. Do you or anyone else know of a way to test for it? If the reaction is that dramatic, I would think they'd develop a test, right? Maybe I'm thinking too much again. ^_^
