I use water (soak) in the food to slow mine down and other reasons. There are also
"brake fast" feeders, muffin tins like above, scattering the food, food toys.
Most of mine ate like that--if it is so fast they choke I step in and do things to slow it down. Eating fast, they can swallow a lot of air which can lead to bloat.
