I'm so sorry to hear this. I sure hope it's not the big "C". Storm also had high calcium levels when he had his bloodwork done the past few years and so he also had another type of test done but I can't remember the name of it. It turned out fine so I didn't worry. This year his bloodwork was fine and his calcium level was high but still within the normal limits. The only thing that's changed has been his diet which is now grain free Innova Evo. I'll keep Mitzi in my thoughts and prayers. Please continue to keep us updated and take care. (((HUGS)))
