When I took my first furbaby in at 4 years she ate fast then vomited it back up.  Vet said
it was most likely that she ate fast because she was used to, as a stray, having to eat
fast to make sure she got food and she would probably ourgrow it.

Well after a while she seen that there was always going to be food there for her and she
stopped eating fast and started keeping her food down.

I would also suspect hairballs especially if kitty stay's
indoors all the time.

I'm not actually sure whether they work or not, but I do buy
Big Mama hairball formula hard tacks during the summer when
her fur sheds the most.
That, and I brush her everyday to get as much loose fur out
of her as I can.

That being said, cats need exercise. They have to get
a daily dose of thier survival instincts (i.e. outside, nature,
things that make them move without being actually dangerous
to them).
After Big Mama eats her dinner, she gets a trip outside to
be active, or I will play with her inside for 10-15 minutes if
the weather is too bad out.
She doesn't always want to go, but if she just sits around
and licks, there is a chance she's going to get sick.
But when she gets active after dinner, the frequency of sickness
is greatly reduced to almost zero.

if its canned food, heat it up in a microwave oven. not to hot that'll
burn the kitty but hot enough to make kitty slow down.
once might be enough

do it too often....... ;)

Give him no food for two days until he learns his lesson not to eat too
fast. This also serves to 'thin up' your cat, always a healthy choice.
