'Lo, FML! Just wanted to jot a quick note of thanks to all of the lovely people that responded to my spleen question. The good news is that I decided to go ahead and have Cassidy's blood sugar levels tested to rule out insulinoma. All went well - he tested at 87, even after a fast. The vet said that sugar levels do vary, but after a four-hour fast his would have been much lower if he had insulinoma. So, thank you for all of your advice and support - you were right - a quick, inexpensive test saved me alot of worry. :) - Kristen ("All's well for now!) Cassidy ("The vet!?!?! Again!?!!?)
