Tinkerbell (the hamster) got out of her cage today and when I went looking for her she had crawled into Fifi's(the cavy) cage. (Fifi has the normal spaced grids for her cage). They touched noses then Fifi followed Tinkerbell around the cage until I took her out. They can each get away from the other. Right now, I'm trying some floor time and Fifi is just following Tinkerbell around. Is there anything wrong with this?
