I took my Tabitha to the vets this morning, she is either 16 or 17, I cant quite remember. She has lost a lot of weight lately and is very vocal, plus she is acting like a kitten again, going out all the time, climbing all over the furniture and eating me out of house and home! She has had a blood test which has shown that she too has an overactive thyroid. Unfortunately, it has caused a little bit of damage to her kidneys, so tomorrow, we have to go back to discuss the treatment. Im hoping that we have caught it quickly enough so that the damage doesn't get any worse. In all other ways, the vet says that she is in perfect health, so hopefully that will stand her in good stead.
