My son Alex starting his business making catnip toys about 3 years ago. He started making them from the fabric scraps from my handbag business, and he still does. These toys are approximately 3" x 2 1/2". These are fill with long lasting catnip pellets. The pellets are made from dried catnip that is then machine compressed into pellets. The wonderful smell that your kitties are so crazy about will last at least one year. These come in assorted colors and patterns. Let us choose one for you. 25% of sales of catnip toys goes to Sweetpea, Friends of Rutland Animal Shelter (Rutland, MA) an other various local animal shelters.
