Welcome to TCS, mardmode! I'm very sorry that you and Sunny are going through this.
This condition is apparently not all that uncommon...if you want to do some reading, Google "ideopathic hypercalcemia" - you'll find lots. There is a dedicated site here
http://felineihc.org/ (There's even a Facebook page - but, not being a FB user, I have no idea whether/not it's a trustworthy resource...for me, that's a "beware zone"!)
I'm no fan of the 'ask-the-expert' type sites, but I did notice something that perked my interest here

| If your cat truely has idiopathic hypercalcemia there is another drug to consider. It is called Fosamax (alendronate) and a vet at Ohio State University came up with a protocol to use in these types of cases. It would be worth mentioning to your vet to see if it is something they have considered. It is only used once all other possible causes of hypercalcemia have been ruled out. http://www.justanswer.com/pet-cat/1v...rcalcemia.html |
I know that "standard" treatment involves dietary management plus steroids, and so it surprises me that your Vet is not moving past the diet management...if I were in your position, I think I'd first look for a cat-only clinic (or Veterinary College) in my area and seek out a second opinion including expanded treatment options.
Please keep us informed as you move forward. I'll be thinking of you both
