Castor & Pollux Pet Works offers the Go Organic Kit, an all-in-one organic diet kit available for cats and dogs. The Go Organic Kit features food and treats from the company's Organix line, the first certified organic food products launched for dogs and cats after the USDA's National Organic Program (NOP) was introduced in 2000, according to Castor & Pollux. Inside the reusable container are both dry and wet foods, treats, coupons and information on the benefits of eating organic.
