I have opened a new thread here:
http://www.pets.ca/forum/showthread.php?t=60971 to continue the
HyperT discussion, I would like to keep this one more on the
CRF discussion
Mad Catter In regards to the BUN, Creatinine and Phos numbers those still all fall in normal range for healthy cats, the USG of course is much lower than it should be however that could be due to infection or the HyperT covering up CRF. I'll comment on the T4 in the other thread linked above
Bear in mind that
if HyperT is masking kidney failure it will show itself within 3 months of having the HyperT properly regulated, so she will need additional testing at that point.
