It was time for my cat to eat her dinner. Her name is Gracie. When it's time for her to eat, she will meow constantly and paw at her food bowl. She also will follow you sometimes. When I noticed her doing this, I walked to the kitchen cabinet where her food is kept and pulled out one small can of tuna and chicken flavored wet cat food, which is her favorite. She saw that I did this and affectionately brushed up against my legs. I opened the can using the pull tab on top of the lid, and used a spoon to scrape all of the food out of the can and into her food dish. She immediately went to her dish, and had eaten all of her food within a few minutes. I also placed water into her water bowl, which she lapped up after finishing her cat food. 
Question: What did the cat eat?
One can of tuna and chicken flavored cat food
