We also have a cat with chronic renal problems. She is 17 (Cali) and has been getting sub cue fluids 6x/week for the last four years. If your little lady is not happy with the RX foods, you might want to talk to your veterinarian about what we have done. Generally, we looks for the lowest protein foods we can get from other companies - and try to keep it down to under 8.5%. We often mix foods too - such as Pet Guard's Venison and Rice Formula (6% protein), with a higher protein food (such as Wellness Herring and Fish). It is a bit unorthodox, but Cali's bloods have been consistent for the last 4 years. Prior to going this route, we tried pretty much the whole gambit. We did the Science Diet (Hills) food, which the cat hated...though I understand that they recently reformulated. We also did the Purina (the best of the lot), and the Waltham Packets (which amounted to them sucking up the gravy and leaving the food).

As to the thyroid meds - are you using the liquid that you put on their ear? LOL, we did that one with one of our older cats...she hated it and seemed to know immediately when we were about to put it on her.
