Hey everyone. I was wondering if any of you have found a good alternative to the traditional hay rack. My girls have a large metal rack I purchased from the official Guinea Pig Cage Store. My girls like their hay rack, but lately they have developed the bad habit of jumping in it to burrow and eat. I really don't like this behavior as it is not safe. Since they love to get in the hay to eat, I've been contemplating getting one of those large wooden hidey houses and filling it with hay. Has anyone done or do this? Any suggestions would be appreciated!
