The hypothesis is that the IAMS brand, which is the most expensive, will have the highest percent of food digested and absorbed through the cat's intestine.

You will label four beakers according to the cat food brands, pour hydrochloric acid and water into each beaker, add the cat food, let it sit for 12 hours, drain the acid, add meat tenderizer, let it sit for 12 hours, strain the meat tenderizer, and measure the weight of the remaining cat food.

You will need 150g of four brands of cat food, 1200ml of hydrochloric acid, a large beaker, pH paper, four beakers, a measuring cylinder, 1200ml of meat tenderizer, tap water, a digital weighing scale, a strainer, and a black marker pen.

The results showed that the IAMS cat food brand had the largest percent of food digested during the experiment.

This science project is interesting because it tests the digestibility of different cat food brands and provides insight into the digestive process of cats.

Variations of this experiment include feeding the cat with dry food, soft moist food, and canned food and examining the differences in nutrient content of various brands of dog food.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
