Hi, I purchased 2 baby chinchillas about 2 months ago and they were 11 weeks old when I got them. They do not like to be touched at all. They run away from me when I try to pet them. When I sneakily pet them from the side of the cage, they think something is touching them and they scratch that part of their body. I've been playing with these 2 chinchillas every morning and every evening since the day I got them. They just don't like to be touched at all. It's really starting to worry me because I don't want to give them away, they cost me almost $400 (cage, food, toys etc). I know they're still babies but they're about 19 weeks old now and they still don't want to be touched. Is this normal and what can I do?
