Various colors. Lanolin has a mild effect similar to catnip and for many cats, all-natural wool toys are their favorite. The rough edges of wool fibers help to clean plaque off your cat’s teeth and keep claws clean while they play. This blend of Himalayan and New Zealand wools is rich in lanolin, which naturally attracts pets and is good for their health. We use safe, non-toxic dyes and there are no synthetic microfibers that may be harmful to your pet if they are ingested.
