FYI - my Vita lost weight for 2 years, I kept taking her in to the vet, having blood work, "all looks fine." Then this year in Feb, when we went in yet again (from 12 pound she was down to 6!), in addition to what the vet did I asked for the Free T4 lab work. It is a part of the thyroid testing. Sure enough, her TSH (total thyroid) is normal, but her Free T 4 (the active hormone) was through the roof! Hyperactive thyroid, which is common in cats as they age.
She is now on meds, but she has really suffered and it will take time to get her feeling better. I don't know why they don't use the Free T4 in veterinary medicine; my doc uses it for me!
