I have a chinchilla. They aren't "cuddly", don't really like being held or touched to mucy. They need to have a AC since anything over 80 can give them heat stroke and or kill them. They need a lot of room to run and jump around so a big cage is a must. They need a high quality pellet and good quality hay. They do better in pairs. When they get sick, they go down hill every fast. I just took mine ot the ER vet this past sunday because he had gotten sick.
I highly recommend if you really want a chinchilla to read up on them over at

The people can be a bit harsh, but they really do care a lot more about the animals welfare... then your own personal feelings.
I love my chinchilla, he is very sweet. I'd recommend getting one from a breeder and not from a petstore since petstore chins are known to be inbred, have major health problems and be a bit crazy and not to tame.
Also if you know ferrets are illegal in CA... DO NOT GET ONE. You will be caught down the road after your friends get word you own one you will be fined pretty good, along with your ferret being put to sleep.
