I am 21 years old. Also, has anyone had their chinchillas just be relaxing and then make a repeated loud squeaking noise for no apparent reason? Anyway, I'm glad i got them, and I also like how when they are tired after being let out to play, that when they go back in their cage they plop down and fall asleep on their sides with their back legs sticking out of their little hut(and sometimes making tiny hopping motions as they sleep)
