Here's a pic of the floor time area they have.
Thank you for the suggestions. I've tried to make it comfortable and interesting w/ plenty of hiding places for them, so hopefully they'll get the hang of it soon! Also, I wanted to know if anyone has had experience with guinea pigs warming up to you. They still run and hide when I pass by the cage and when I take them out, they hate being picked up. Any tips on how to make them more comfortable with me or should I just be patient?
