Carolyn,
Glad to hear how Latte is doing. I won't repeat what I said in my email here re BIV, you already have it.
The reason she likes it here so much is YOU. That should be obvious. Latte has lived this long post-Dx, with what I can see by your updates/emails is a good quality of life, because of the exceedingly fine care you have given her. You have researched her condition to infinity; mobilized State Attorneys General forces not just for her, but for other kitties; made huge life changes for yourself, not to mention numerous personal sacrifices; and just "been there" for her. She could not have asked for a better Mommy than you.
