Cass,
I don't know that vomiting is a sign of HT. Tex has always vomited. Always. But, it did get to the point where it was very frequent. I had him tested for lots of stuff, but, everything was negative. Since he has been on the HT meds, the vomiting is less, alot less. But, there are some other changes, too. He eats a prescription diet...but, I really don't know how that really helps, since I feed him kitten food, and baby food, too. It is kind of like saying the HT meds helped his vomiting, but, I can't say that vomiting is a sign of HT...I don't really know. I used to think it was an allergy to beef, then, I thought it was some type of acid reflux. It does seem more prevelant in the am, and I can nearly count on vomiting if his food bowls are empty in the am, when I wake up, and he gets fed. He seems to need food in his tum tum all the time.

How is that for an answer?
