Wow, this is amazing. I'm so glad to know I'm not alone with this frustrating problem. It sounds like Tex and Ripley are long lost brothers.

I will check with my vet about getting a thyroid test on Rip and I will take your suggestions Jen about feeding him slowly. He just had a complete dental last spring and everything was fine, they cleaned but didn't have to extract any teeth but feeding him small sized food will probably help too.

It's funny, for a while when it was just Ripley, I bought cat food based on it's color so it wouldn't stain my carpets too badly. I'm pickier on the food I feed everyone now but I still hesitate to give him anything too dark.

Poor Rip is sleeping off his bad day right now so maybe the worst is over for now. He always acts like a baby after he's thrown up and today is no exception.
