They may look like chubsters, but most of that is just fur. Never underestimate their escape-artist potential. Of course, if a chinchilla is kept permanently enclosed in a tiny cage, this exuberrant personality will be stifled. A chinchilla really needs a very large cage, plus the opportunity to get out and romp daily. As with most pets, the more you put into the relationship with your chinchilla the more you will be rewarded by the emergence of its full personality and its devotion to you.
Chinchillas can become very attached to their keepers.
They will sit in your lap or on your shoulder. Much depends on how it was socialized as a baby. If it was cuddled and held from day one, it will always be trusting and friendly with humans. However, even a standoffish or frightened chin can usually be won over with lots of caring attention. If you can't put a lot of time into the relationship with your chinchilla, it is best to get it a partner.
