Changing the protein source of your cat’s food will also help prevent him from developing food allergies to certain proteins. For example, if his current food is chicken based, try one that’s not too similar, such as seafood or beef based.
When you decide to change his food, it’s important to do it gradually to minimize digestive problems for him.
Here is a schedule to follow when changing your cat’s food:
First Day-90% of his current food, 10% of the new variety
Second Day-80% current food, 20% new variety
Third Day-70% current food, 30% new variety
Days 4-10-Continue gradually reducing current food while increasing amount of new variety until change is complete
Watch his litter box to be sure he’s not having digestive issues with the change. Following the gradual conversion schedule will give your cat a chance to get used to the flavor change and look forward to a new taste sensation.
