Your cat’s personalised daily-serve pouch size is calculated using the information you tell us about them during sign up - such as their age, weight, activity level and current body condition. This ensures that every cat gets the right amount of daily calories and nutrients just for them. We use our own algorithm which was developed alongside Dr Justin Shmalberg, a Board-certified vet nutritionist expert, to ensure your cat gets the perfect amount of calories they need for their own particular energy needs. As we use daily-serve pouches you’ll share one pouch over breakfast and dinner time, or feed smaller meals throughout the day if your cat prefers. It's a good idea to keep your cat's weight and activity level up-to-date in their profile. If they're a kitten or you are trying to achieve a healthier weight and body score, our algorithm will adjust the pouch sizes (and the cost of your boxes) based on this information.
