ive had my first chinchilla for about 4 months and everything with him is perfectly fine. then i recently got a 2nd chinchilla they are both separated at all times and he is also well behaved and normal personallity. last night while he was out and playing my gf accidently stepped on him and he lost a huge clump of fur he wasnt injured by it and is as normal as when we got him he just has a small bald spot on his side. you cant see unless you move his fur around. he is running around normal like nothing happened he isnt acting strange he is still friendly with us. i was playing with his feet and his sides to see if anything was broken and he didnt make any sound and is still jumping around and playing. i was just wondering if he could catch anything or get a parasite with the missing fur. i read it could take a few month to grow back.
