Ah yes, nothing like a nice puddle of cat puke to brighten the day... Or several, more likely.

If it's only every 3 or 4 days, it's probably not kidney disease. When my Roscoe had acute kidney disease as a result of the Great Pet Food Poisoning, he was throwing up every few hours, to the point where it was dry heaves or just a bit of mucus (still unpleasant to clean up, mind you...), but now that the kidney thing is basically under control as a result of hydration and diet, he just throws up every few days. Usually in several spots in quick succession, just to make things interesting.

My previous cat gave lots of warning when he was about to heave -- enough time to move him off the carpet. Roscoe offers no such courtesy, and has managed to mess up every carpet in the house at one time or another. What a charmer.

I do think it has to do with eating too fast. I don't have a place such as WYSIWYG has for broadcast feeding, but I think I might try Kat's idea of putting rocks in his dish.

Good luck, Bobert.
