We are measuring in our clinic TT4 just before the treatment from all cats what are coming to radioiodine (isotope I-131) treatment, to avoid any misunderstandings.
We require that owner should bring the food for own cat enough for 5 days.
The treatments with radioiodine are 1-2 per month in groups of 3-4 cats.
In case a cat needs the radioiodine treatment urgently we will always try to fit it in the next group or to organise an extra group.
