Frequently Asked Questions

Just like people, eating amounts vary from pet to pet. Most Hill's pet foods have a feeding guide on the package to help you determine the proper amount to feed your pet. Please keep in mind that the feeding guide is intended only as a starting point, and you should follow your veterinarian’s recommendation based on your pet's specific health needs.

Bags of dry Science Diet, Healthy Advantage and Prescription Diet cat or dog food should be stored in a cool, dry environment under 100°F (38°C)? This is to prevent destruction of vitamins and oxidation of fats leading to rancidity. Pet foods will retain their best flavor if stored in the original bag, which provides a fat barrier. Storage at temperatures of 120°F (48°C) for more than 48 hours can accelerate the normal degradation or destruction of the vitamins.

Store the food in a cool and dry environment. It is best to store the bag off the floor to reduce potential infestation.

3 Steps to Transitioning Your Cat to a New Pet Food

Determine the right amount per serving
Make sure that you’re not overfeeding your cat and the portions they get are appropriate for their weight and health needs. A good way to start is by checking the feeding guide on your cat’s food packaging, but your veterinarian will have the best recommendation.

Follow this 7-day transition schedule
Over a week, gradually decrease the amount of your pet’s current cat food while increasing the amount of new cat food. For finicky cats, the transition time could take 10 days or slightly longer.

Add a little wet food if needed
Cats can be wary of changes, especially new foods. A little canned food can go a long way in getting them to try a new food. If you do add wet food, take those calories into account so you don't overfeed, and make sure to check with your vet on the proper amount.
