We had a bouquet of flowers on the dinner table near the cage and Potato seemed very interested. So I held him up and let him get a good look. The pigs prefer green veggies, and the only flowers they eat are the ones on sprouting herbs, so I don't think he wanted to taste them. Maybe he was just curious what's so colorful.
I was really out of ideas that day. He did a good job trying to come up with something different.
