Abstract: A pet toy is configured for receiving a food item. The pet toy comprises a durable and resilient outer wall, an interior chamber, and at least one opening for inserting and/or retrieving the food item. The outer wall can comprise one or more regions of greater rigidity and one or more regions of less rigidity. The pet toy is further configured to selectively retain the food item during a pet's play with the pet toy. After repeated or sufficient compression of the pet toy, the food item can be dislodged, in either a single piece or in multiple smaller pieces, from the pet toy as the pet's reward.

Abstract: A pet toy is constructed of a resilient material that stretches and returns to its original shape when at rest. The toy further has a spiral, coiled, or wound shape that channels or directs stretch in a particular direction. The toy has stretch or shape-changing ability and can change in length by one and one-half times or more. In some instances an object can be used with the toy and be retained within an interior space of the toy.
