This satisfying chew treat is made from all-natural, bark covered fruitwood that your small animal will find absolutely irresistible. And, chewing helps prevent overgrown incisors.Chemical free branches are harvested from a sustainable wood source. Branch Bites are made from gooseberry fruitwood trees. The branches are pruned each year to increase the production of the berry, which is used to make jam, jelly, and preserves. The routine pruning process insures the health of the plant, an improved fruit crop, plus this creates a regular supply of branches that rodents and rabbits instinctively need and enjoy to chew on.Each Big Branch Bite features a center hole to make them easy to slide onto a Super Pet Ka-Bob treat dispenser and hang inside your pet's home. Sold separately, check it out under "Feeding Accessories: Feeders & Waterers".Big Branch Bites are sized for rabbits, guinea pigs, chinchillas, and other critters.
