Monnet, 2018) indicated that diets high in grains do not align with the natural dietary habits of cats.
For pet owners considering Science Diet, it is vital to assess individual cat needs. If a cat has specific dietary requirements or allergies, consulting a veterinarian beforehand is recommended. Additionally, reading ingredient labels and comparing other brands with higher quality standards may be beneficial.

How Can You Safely Transition Your Cat to Science Diet Cat Food?
To safely transition your cat to Science Diet cat food, follow these steps: start with a gradual introduction of the new food, monitor your cat’s response, and adjust the feeding routine as needed.
-
Gradual introduction: Transition to a new food should take about 7 to 10 days. Start by mixing a small amount of Science Diet food with your cat’s current food. Increase the proportion of Science Diet gradually each day. For example, begin with 25% Science Diet and 75% old food for the first few days, then move to a 50/50 mix. This gradual transition helps avoid digestive upset.
-
Monitor your cat’s response: During the transition, observe your cat for any signs of gastrointestinal discomfort, such as vomiting or diarrhea. If these occur, slow down the transition by maintaining the current mix longer before increasing the Science Diet portion. Each cat reacts differently, and patience is important.
-
Adjust feeding routine: Maintain a consistent feeding schedule to create a sense of stability for your cat. Try to feed your cat at the same times each day and in the same location. Monitor portion sizes according to guidelines on the Science Diet packaging, adjusting as necessary for your cat’s age, weight, and activity level.
