What is the best way to switch my dog or cat from Castor & Pollux food to Merrick food?

Gradually! Start by mixing a small amount of their new Merrick recipe with Castor & Pollux food. Then, over the course of seven to ten days, increase the amount of the new Merrick food while decreasing the amount of the old recipe until you have 100% new food in the bowl. Review the packaging for recommended daily feeding amounts. If you have any questions about transitioning, contact us through our online support form or by calling 1-800-875-7518. If you’re not sure which recipe is right for your pet, we’re happy to recommend recipes based on your pet’s needs.
