Hi,

My cat buffy frequently throws up the food she has just eaten, within
20-30 mins of eating. This leaves a mess, unless my other cat eats it
up, which she is kind enough to do on most occasions.

What I notice with buffy is that she doesn't really chew her food and
she wolfs it down. Someone told me also that she might be eating too
fast so to serve smaller portions, but unless I watch over every bite
she eats, and make sure she takes time between bites, I haven't been
able to eliminate this problem.

Have you tried feeding canned food? Does she have hairballs when she
vomits or any other symptoms?
