  • Patent number: 5033410
    Abstract: Rope woven from semirigid, breakable and elastically deformed synthetic fibers, such as polyethylene fibers, is broken into discrete segments. The rope is woven with portions of the individual fiber's surface exposed and remaining portions of the same surface-exposed fibers embedded within the mass of the rope. The rope is impregnated with a flavored media having a taste desirable to animals. For example, a braided or woven polyethylene fiber rope having individual strands on the order of one eighth of an inch or less is boiled in equal parts of a flavoring media and water for a period of about three hours. Exemplary flavoring can include cod liver oil alone for cats and a combination of cod liver oil and beef broth for dogs. The rope segment can optionally be tied with knots at the distal ends and sealed at the point of severance, as by searing with heat the severed fiber ends.
