What is an owl pellet? An owl pellet is the indigestible substances that the owl spits out through its mouth, out of the body, to dispose of parts that can not be eaten in a form of a pellet. It is like a hair ball from a cat. Like many other birds, owl's don't have teeth, therefore, they cannot chew their food and break it down into smaller digestable pieces, so they swallow their meal whole. Owl's use their sharp beaks to rip apart their prey and eat the large chunks of it. The owl slowly digests soft portions like meat, and separates it from harder portions such as bones. It soon regurgitates the hard portions as well as fur and feathers.
