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

Gradually! Start by mixing a small amount of Castor & Pollux food in with their current food. Then over the course of seven to ten days, increase the amount of the new food while decreasing the amount of the old until you have 100% Castor & Pollux in the bowl. You can refer to our recommended schedule for a transition to a new food. Review the package for recommended daily feeding amounts.
