Yes, there is a member named Growler. She has had alot of success with it and is soooo very knowledgeable. She normally logs on at night, but I haven't seen any posts by her lately so not sure if she is very busy with Christmas right now.
She may want to see the results of your kitty's bloodwork and urinalysis so perhaps if you can post that, she may be able to give you more advice.
Here is her thread:
