HOW LONG WILL IT TAKE MY CAT TO GAIN WEIGHT AND RETURN TO NORMAL BEHAVIOR?
We see the thyroid levels return to normal usually in 1-2 months. That is why we recommend a recheck of the T4 levels with your regular veterinarian at one, 2, 6 months and 1 year post radioiodine treatment – with yearly rechecks after that. If the cat was not able to tolerate a Tapazole trial, or even if a Tapazole trial was performed and the thyroid (T4) level did not return to normal, we also recommend rechecking the BUN, creatinine and urine specific gravity (kidney values).
