Birds love the challenge of unstuffing their Kong. Begin with a mixture of nuts, fruit and manufactured bird treats and fill the cavity. Make sure to leave a nice tidbit sticking out of the Kong. A stuffed Kong can provide much needed entertainment to prevent cage vices such as feather plucking, boredom, aggression, etc. Kong chew toys have two main shapes.
People are most familiar with the patented honeycomb shape.
All Kong toys provide needed jaw exercises. Kong is a small company and has not had a need for one, since most of our communication is with distributors of our products rather than consumers. We always like to hear from pet owners and see pictures of pets enjoying their Kong Toys. Although we know florescent colors may be easier for people to see, the same is not true for dogs. The shape and unpredictable bounce make the Kong seem alive.
