貓是肉食動物,你必須給他足夠蛋白質,否則他會營養不良,身體更差。但是如果他 phosphorus 高,你要給他 binder to reduce phosphorus to normal. Once calcium and phosphorus are normal, you can ask the vet if Calcitrol could help.
For hyper T, you can have the medicine compoundd into trandermal ear gel to be applied to the ears. The negative side effects are less harsh than oral medicine. You can also ask the vet whether i131 would help. That is the ONLY cure for hyper T.
