Spot is my hyperthyroid baby. I don't know his age ("older than 10") since I found him abandoned last year. He had radioiodine treatment in June, but his thyroid went up after treatment, so he's been back on the methimazole (Tapazole). At the end of July, his specific gravity of his urine was 1.034, well within the normal range. By the beginning of September, it had dropped to 1.024. It has been dropping ever since, and it is currently at 1.017 as of today.
His kidney values have always come back as normal, with his creatinine tending toward the low side. His behavior lately has been kind of antsy. He has been chasing my other cat around the house and picking on her a bit. He has been very cuddley with me most of the time. It's not his thyroid, which was actually low when we tested it two weeks ago (we lowered his dose and tested him again today to be sure it doesn't shoot up again).
Does anyone have any ideas as to what might be going on with him? I haven't been able to find much information about low specific gravity levels other than in connection to kidney disease. Since his kidney levels are normal, we don't think he has CRF. I'd love to hear suggestions from anyone with similar experiences or stories.
