A chewable, biodegradable article for use as a pet toy comprises a matrix made of a natural polymer, a synthetic organic polymer or a mixture thereof, a natural or synthetic fibrous material that comprises fibers and that is bonded chemically or physically with the matrix material, and, optionally,
A chewable, biodegradable article for use as a pet toy comprises a matrix made of a natural polymer, a synthetic organic polymer or a mixture thereof, a natural or synthetic fibrous material that comprises fibers and that is bonded chemically or physically with the matrix material, and, optionally, includes one or more microbe inhibiting agents that inhibit the growth of microbes in or on the article. The presence of the fibrous material inhibits formation of sharp edges upon breakage when the article is chewed, thereby rendering the article safer when used by pets. Also disclosed are processes for manufacturing the above article.
