How to Switch Your Cat’s Food
It’s always best to transition your pet’s diet slowly to avoid potential stomach upset
and allow your pet’s digestive system to adjust to any new ingredients.
Days 1-2
Introduce Purina ONE to your pet in small amounts, still feeding primarily the old food.
Days 3-4
Feed a little bit more Purina ONE to your pet each day.
Days 5-7
Gradually increase the amount of Purina ONE food and decrease your pet’s former food until you are feeding Purina ONE exclusively.
Days 8-10
By now you should be feeding your pet exclusively Purina ONE.
