Aaaaaw lucky you. Oki dokes a few basics for Chinchilla care
1. Chinchilla proof everything as they will explore everything with their teeth especially wires
2. Get a marble slab to keep it cool and place the slab in fridge every day to cool it down
3. Offer a daily dust bath of approx 20 mins, any longer andit gets stuck in their dense fur
4. Offer a high fibre, high protein diet and avoid low fat and moisture and definitely no greens, peanuts or sunflower seeds as they cause colic and bloat. A Chinchilla pellet is best - about 1 tablespoon a day for an adult, also offer good quality fresh hay every day.
5. You can use applewood or rodent toys for them to chew on as their teeth grow fast and they need things to gnaw on
6. Before you let it out for exercise (which it should have every day) you need to know you can catch it again. Gain it's trust first by offering their favourite treat (usually a raisin or sultanna) let them get used to taking this from your hand then start by gently stroking it under the chin. Once it is doing this let it out in a small area supervised and again keep offering the treats so it associates coming to you with getting a reward. When it has been doing this for a while you can attempt to pick it up - but please NEVER pick it up by its tail as some will advise you. You can support it by holding the base of it's tail only.
7. Be warned that if it feels threatened in any way it will stand on its hind legs and spray urine at you.
If it starts to lose it's fur or pull it out, it is an indication of poor diet or stress
