Adult Feeding Guide: varies based on age / activity level / lifestage
The best way to transition to a new food is to switch gradually over the course of 7-10 days. For example, make a mixture that contains 25% of the new food and 75% of the old food and feed that for three days. Then make it 50-50 for three more days, then 75% new food and 25% old food for three more days. If your cat seems comfortable with this progression, you can start feeding 100% new food. If at any time your pet starts vomiting, has loose stools, or appears constipated, slow the rate at which you are switching the food. If problems continue to occur, consult your veterinarian.
