Today I was visiting my piggies and got their bowl to refill it with pellets. It was upside down. I turned it over and it looked like giant pellets were in there along with pellet mush. I don't feed my guinea pigs too much or too little, they have a rather small bowl that I fill with food everyday, and I also give them a carrot or a couple of grape tomatoes and sometimes celery or lettuce and cilantro. They also have an unlimited supply of timothy hay. Am I doing something wrong? Was it throw up?
