Frenemies

Sophie (chinchilla) and Elsa (cat) are extremely curious about each other. Elsa will reach her paw in and gently tap Sophie, which makes Sophie scurry at top speed to the top of her cage, but then she comes back right down and sticks her nose out at Elsa. Then if Elsa tries to put her paw back in the cage, Sophie tries to bite her, which scares Elsa away. Then they repeat the whole process. It's really entertaining to watch.
