My friend has left her sweet little guinea pig in my care for the next month while she travels home over winter break. She left me with Timothy hay and a huge thing of bedding. Friend said to give her as much hay as she wants every day, and a carrot sometimes as a treat? I've never had a guinea pig before, just a hamster when I was young. Is the hay, and some carrot every few days, really enough for her? I'm absolutely terrified of not keeping this sweet little girl as happy and healthy as I can. I also have 2 young cats (who aren't allowed in the room the guinea pig is in) who are loud and crazy, so she's already a little stressed out from hearing them wrestle and yowl beyond the door.
