January is such a busy month for me I hadn't read this thread before today.

I will be thinking all good thoughts for Misty and her vet visit tonight.

You have been given excellent advice by everyone here, so I won't add to it........getting the second opinion is such a good idea.

When my cats have been ill, it breaks my heart, so I offer you understanding and hope that Misty is back on the right track and getting better.
