摘要：A molded pet toy includes sections or layers of various hardnesses. The pet toymay be constructed through known injection molding, transfer, or compression moldingprocesses. The layers and sections typically have varying hardnesses which facilitates use
of the pet toy for a specific purpose. For use as a pet toy, an optimal arrangementprovides that the outermost section or layer is of a lower hardness, while the innersections or layers have a higher hardness. Durability of the pet toy is increased throughthe molding process which prevents separation between the layers. The pet toy ispreferably shaped aerodynamically so it may be easily thrown by a user.
