So my guinea pig has access to unlimited hay but I'm wondering if that is enough. I know guinea pigs' teeth continuously grow and they need to chew to manage them; is just the unlimited hay enough? I've tried wooden chewing blocks but she just pees on them. She had a wooden hidey house but she was staying in it constantly and she peed on that too. I've also given her a piece of crumpled up paper she likes to occasionally chew on. If what I have isn't enough does anyone have any recommendations for chews that she may like?
