How do I switch or transition foods for my cat?

How do I switch or transition foods for my cat?

Ideally, a cat should gradually transition from her current cat food to her new cat food to avoid digestive upset or food avoidance.

To begin the transition, mix your cat’s current food with her new food. Gradually decrease the amount of the current cat food while increasing the amount of new cat food. Continue to do this over a 7-day period.

To help you with the switch and cat food transition, refer to the 7-Day Transition Schedule below.

7-Day Transition Schedule for your cat







Be patient. For finicky, older, or cats with health conditions, the transition time could take 10 days or slightly longer.

Remember these tips when switching cat food:

  • Kittens should transition to an adult cat food at 12 months of age to ensure they are receiving proper nutrient levels for adult cats.
  • For cats who are 7 years or older, they too should switch to a mature adult or senior cat food that ensures that they are receiving the appropriate level of nutrients for that older lifestage.
  • Pregnant or nursing cats need energy-dense foods with increased calcium content so be sure to transition them during this special time to a kitten food.
  • If your veterinarian has recommended a therapeutic cat food for a specific health condition, please be sure to discuss transitioning her cat food in detail. There could be some special considerations and suggestions to ensure success.
