December 6, one pitiful cat, 2 lbs down, lank coat, not eating, and with a wretched reaction to thyroid medicine. Just a month later, he's back to his full 10 lbs, has a coat like silk, and his bloodwork came back with everything in normal ranges--even the albumen that was elevated has come down to where it should be. He's happy and I'm ecstatic. If you have a cat with a thryoid condition, I HIGHLY recommend the treatment. Yes it's expensive--although cheaper than daily meds for the life of the cat, esp'ly if you have to use the ear gel--but the results have been fantastic.
