I'm very lucky in that Cheech is very open to pretty much anything. He will sleep through most music we play in our room, computer games and isn't bothered by guests. We just have to make sure we keep an eye on him and find out what bothers him. There is one piece of music he hates for no apparent reason and also for no reason we can tell he hates my boyfriend's little brother even though he's fine with other kids. The best piece of information I have been given from people on this site is just watch your chinchilla, they will tell you when they are happy and when they're not.
I don't know if you have a book on chinchillas but here are few things I think are important:
Make sure the floors of the cage are replaced with pine shelves as soon as possible
Make sure you have a good food for your chin without too many treats
Make sure you have fresh hay and water available at all times
Make sure your chin has some toys to keep himself amused - wooden parrot toys and cardboard tubes are great
If you want to let him out eventually make sure you tame him first by letting him get used to your hands and if you do, make sure the room is 'chin proofed'. If you need any help making a room chinchilla proofed just as one of us here.
If you let him out only do it for a short amount of time because he may not be used to life outside the cage and may wear himself.
Make sure you have a wooden box/house in the cage for you chin to sleep in
Keep as regular a routine as possible because chinchillas like routine. Feed him at the same time each day etc.
Ask an experienced member here how to pick a chinchilla up, if you do it wrongly you can actually break their ribs because they have floating rib cages.
A healthy chinchilla will do a LOT of poos.
If I've missed anything then I'm sure someone here will be able to let you know. I am also a fairly new chinchilla owner and you won't be disappointed they are very loving animals and so much fun to watch playing outside of the cage, especially when they jump from place to place, even running up to and jumping off walls. You just have to remember that they are prey animals and are quite fragile.
