In march I took one of my cats age 9 to the vets due to a small lump on her leg with recent episodes of sickness/ dhioreah constant hunger with weight loss.
Was told she probarly had hyperthyroidism but also she has a heart murmer.
She has since been on meds for thyroid, started out on 2.5mg x 2 daily which increased to 3mg x 2 daily then 5mg x 2 daily.
She put a bit of on weight up untill last month and then lost a bit.
She has improved in so much as not crying for food constantly, no more vomiting etc since March.
This week had follow up blood test i was told T4 levels are still very high 101 instead of between 19-62.
She has put a tiny amont of weight back on and although not back to usual weight she is not really underweight.
Meds have to be increased to 6mg x 2 daily now, to be seen in 4 weeks for blood test.
I am sitting here thinking surley an increase of 1mg 2 x daily isn't going to be enough to get her levels down to 62 or lower in 4 wks.
So why would they not increase it a bit more as they did when it increased from 3mg to 5 before.
Tests of the small lump on her leg previously came back inconclusive, but due to the thyoid issues they couldnt and still cant sedate her to remove it as a precaution or take a heart scan.
Appreciate any advice or suggested questions I can ask when I call the vets to ask why such a small increase etc.
