Worried about M cat.

[Cammy]

Maybe when M cat gets her meds back on schedule and her main person around, things will be okay. If M cat is hypothyroid a few days off meds could increase the size of the thyroid gland which is why the voice is quiet. In humans, an enlarging thyroid causes deepening of the voice. Sounds like a wait and see thing. Give the meds at least a week and then decide if vet inspection is needed. Of course if M cat stops eating or has trouble swallowing, this is much more urgent. I'm not an expert, but I have thyroid issues and lots of non-verbal lifeforms in my life, so this is all based on personal experience. Hope it helps.
