Good for your cousin for saving him and giving him to you. I have saved I dont even know how many chins from our shelter, for one so they dont become euthanized, and for two because I dont want just any random person adopting a chinchilla because they think they are cool and different, and because its only 50 bucks to adopt at our shelter, anyone can go and get one when they normally wouldnt bc of their normal prices.
It just worries me like that. I dont know why. Ive seen people who have no idea what a chinchilla is go into a shelter and just adopt it bc they can "actually" afford it this way. And Ive also seen them bring the chin back too because they were too much for them to handle and they didnt know how much they needed to know to care for one.
But Congrats on him. He sounds really nice and he looks handsome. Good Luck with him and we are all here if you have any questions!!
