Today I was chopping up my piggie's fruit and veggies when I walked into the room and he shrieked! It was almost like he was in pain! Well, I sat down and gave him his food and he completely ignored it. I was getting up and bumped into his cage, there is a kabob bell that I usually hang his veggies on and when I bumped into the cage the bell rang and he quietly ran to his veggies. Not sure if the thinks that it's the signal to eat veggies or not!
