I'm so sorry for you and for Rex. I wish you had a vet close by that could give you some help and support. I think a few people here do have experience with Iggys and hopefully one of them will respond. But know that I will be keeping you and Rex in my thoughts and prayers. It's the hardest thing to see our beloved "kids" ill And I'm sure his life with you were the happiest years of his life. Gentle hugs to you Rex. Love, Sandra
