This reminds me of an idea I had for a chain of restaurants located wherever supermodels and actresses gather. It would be called the Scarf & Barf and feature an all-you-can-eat menu. Each table would have a generous supply of barf bags, thus eliminating (*snort*) the long lines for the bathroom. No more waiting in line to barf means less caloric intake -- perfect!
I (and vets I have known) draw a distinction between immediate regurgitation of undigested food and vomiting of partially digested food.. the latter is usually due to hairballs, while the former can be due to eating too fast or as my vet said, if the cat is nervous because another cat is trying to steal his or her food, that can result in a snarf-n-barf.
All cats are more or less hork-prone, trivet. My personal theory on this is because their digestive systems haven't evolved past being pure carnivores and thus all this grain-based manufactured food does not agree with them. My cat sadly has an eating disorder - when he wants attention he does a "Snarf and Barf" maneuver where he hoovers a large quantity of food and then immediately regurgitates it, preferably somewhere that will cause me the most possible distress, such as the couch. He has learned that if nothing else works, I will certainly stop whatever I'm doing to deal with the puke.
