Our Jumbo Grape Vine Sticks are a favorite with bunnies who love to chew bark. You'll get a bundle of three Jumbo Grape Vine Sticks tied up with raffia. Our Jumbo Grape Vine Sticks are approx. 6" long and a full 3/8" - 1/2" thick. These aren't little twigs, these are nice thick sticks to provide great chewing fun and they are great for keeping your bunny's teeth in shape!
