I wish I had the answer, but unfortunately I do not. However, there are alot of good suggestion in here.

I just wanted to let you know that Bob used to puke alot and then I got hairball treasts and that has slowed down alot. Now he only gets sick if he eats too fast.

Joey is my puker, or at least was. I used to be able to count on Joey ouking at least once every couple of days, sometimes daily. The hairball treatments help a little, however it was still faurly regular. Then she got sick on Thanksgiving, and ever since she has come back from the vet she has not thrown up except for the couple of days at Christmas. I have been feeding her I/D food. So it may have been a sensitive stomach all along.

Good luck and I hope you find a cause and are able to stop or at least slow the tide.

Just a suggestion, get a Bissel Little Green Cleaner. I got one for our RB Flicka when she had kidney problems, and it is great for cleaning up carpet messes. I don't know what I would have done without it.
