What do guinea pigs like?

Guinea pigs like food. They like their hay and their pellets. If you give them veggies from the fridge, that will be a pig trigger for them. Some of them like attention, pets, screeches, and a wide variety of things. I had one guinea pig that loved to cuddle and would make that little chirping noise when I cuddled and rubbed behind her ears, and then I couldn't even pick up the other one. She'd run away from me. So they have very different personalities across the board.
