How to prepare your cat's meal?

MEASURE: Prepare your cat's food amount as shown on the pack. It is important to measure the right quantity to avoid overfeeding. Divide that portion over at least two meals per day.

MAKE SURE TO ALWAYS PROVIDE FRESH WATER: No matter how you feed your cat, it is important to always have fresh water available.

How to help your cat transition to a new diet?

Changing your cat's diet can make a real difference to their health but remember that any transition has to be smooth and gradual. Combine old food with new, increasing the ratio every 2 days until your cat has fully adapted to their new diet. If you have any questions or concerns about your cat's health, please consult your veterinarian right away.
