All cat treats are grain-free, gluten-free and dog friendly too as catnip is not harmful to dogs in small quantities. You may request them be made without catnip for your cat/dog. They are dehydrated so no refrigeration is required & can be kept on the shelf, in a cool, dry place for up to 2 months. They come in 3oz or 6oz bags. You may request them be made undehydrated, which will require them to be refrigerated. Ingredients & health benefits are listed under each treat. These make great training treats for dogs!
