Abstract: An aerodynamically interactive artifact is proportioned to experience at least one of tumbling, fluttering, and autorotating motion when subjected to free fall in a gravitational field. Suitable shapes include films, strips, butterflies, birds, and the like. The artifact may be contain a neutraceutical, may be dissolvable in pet saliva, and may provide an olfactory sensation for a pet. Dimensionless parameters such as Froude number and length-to-thickness ratios may be used to select aerodynamically interactive motions.

Abstract: A dog chew treat is fashioned from a composition comprising sugar, fiber, and flour. Preferably, the sugar is dextrose, and the flour is pre-gelatinized wheat flour. The composition may be molded into the shape of a bone, or other treat. A palatant coating may be applied to the molded product. Colors may be added for different aesthetics such as a marbling pattern. Functional ingredients may be used to provide health benefits.

Abstract: An extrusion process incorporates a forming manifold where a tubular flow of a second material is intermittently interrupted while a core flow of a first material is discharged substantially continuously. Subsequently, the core flow is severed to form individual food items or treats for humans, animals, and the like, where the tubular flow results in an outer component surrounding an inner component which protrudes from one or both ends of the outer component. Material of the core flow is bone-like, while material of the tubular flow is meat like. Material of the tubular flow may include material from the core flow subjected to mixing in a static mixer to achieve a marbled texture of the outer material.
