Digestion and cat foodFeatured science projectScience project video


The hypothesis that the IAMS brand which is also the most expensive, will have the highest percent of food digested and absorbed through the cat’s intestine, is proven to be true.

Cat food comes in the form of dry food, soft moist food and canned food. Dry food is crunchier and can be stored for a longer period of time than other types of food. Soft moist foods taste better and are convenient to serve. Canned foods taste the best but they need to be refrigerated once the cans are opened. All of the 3 types of cat food provide a cat with enough nutrition and ensure that it has a balanced diet.
