By choosing to feed your cat PRO PLAN you can be reassured that our tailored nutrition will have a positive impact on your cat's long-term health and well-being. Although you will be keen to see the difference PRO PLAN can make in your cat, please allow 7 - 10 days to transition from their current food. This enables your cat's digestive enzymes to gradually adapt to the change in ingredient and nutritional content, assisting with the proper digestion of the food and helping prevent stomach upsets. Each day, simply feed a little less of the previous food and a little more of PRO PLAN until you are feeding PRO PLAN exclusively."
