Separation??

Okay so I'm at a bit of a crossroads. I want a Chinchilla and have sufficient time to take care of him or her, but I'm in college and when I go home for the summers, I stay in a house with no AC! I understand that chinchilla'so cannot be in extreme heat, so I'm wondering if I could have a friend watch him/her for the summers? I don't know if that long of a seperation would cause the chinchilla to become confused or nervous, or if he/she would be fine, as long as my friend gives him/her lots of attention! Please help me! I don't want to confuse the chinchilla by having it with me for 9 months out of the year and with a friend for 3 months, but a chinchilla sounds like a wonderful pet to have!

Thank you!
