Hyperthyroid Cats
Many years ago my own cat Callie had been losing a bit of weight each year even though her dietary intake had not changed. She started to drink more water and seemed a bit nervous to me. I palpated her neck and thought I felt an enlarged thyroid gland. She had started getting very vocal and was wandering around the house at night meowing for no reason ( a symptom that veterinarians often miss) so I did an x-ray on her, a urinalysis to check for kidney function and turned in blood work to check overall health and for hyperthyroidism and renal failure. Sure enough, her thyroid levels were off. She was hyperthyroid.
