This behavior is certainly common, and is usually a matter of conditioning. Best suggestions for deterring food-inhalers are as follows:

★  Avoid feeding large chunks, and instead, break up food

★  Increase the number of daily feedings, without increasing the overall feeding amount, to lessen hunger between meals

★  Spread food out, forcing your pet to visit all of it before finishing

★  Feed from an easy-to-clean slow-feeder bowl (there are many options)

★  If all else fails, you may feed by hand. Some pets are even comforted by this.
