Dammit!!
Our matriarch Alley (about 12 years old) was diagnosed with a hyper-thyroid. She too has steadly gotten thinner and frail over the last several months. Right now we're giving her 1/2 a tablet twice daily of "Methimazole". On Nov 1st she gose to vet for another blood test. Her appitite has always been good and it has'nt changed so I guess thats good.
We found her while we were living in Pennsylvania when she was about a year old. She was abandonded.
I guess its only a matter of time for her.
