Over the next few months you'll notice some changes to your puppy or kitten's usual Hill's Science Diet food.
What has changed?
The main change to Hill's Science Diet Puppy and Kitten products will be the addition of ActivBiome+ , Hill's breakthrough blend of prebiotic fibres to support your pets gut microbiome and digestive system. As these foods will have a new recipe, it is recommended to transition your pet gradually from the old to new food to avoid digestive upsets.

Other changes you may notice include:
Updated packaging to highlight the key benefits of each product
Updated feeding guide
Minor kibble size changes (within 3mm of the current size)
Variation in colour

What do I need to do?
If you have an autodelivery with us we will send out the new products in your regular order as they arrive in our warehouse. Check the table above and if a transition is recommended for your pet's food, transition them to the new formula over a period of about 7 days to minimise any tummy upsets and to ensure they accept the new taste or texture of their food. For detailed instructions on how to transition your pet's food, please see How to Introduce a New Food to Your Pet.
As the feeding guide for some products has also changed, check the new packaging to ensure you are feeding your puppy or kitten the correct amount. If you are unsure, consult your veterinarian or a Pet Circle Vet for advice.
