I adopted my 1 1/2 year old chinchilla over a week ago and I think I might have given him too much freedom too soon. I started out by offering him treats which he didn't mind taking but after I gave him the treat he would just go back into his little house and ignore me. Now when I stick my hand in his cage he will sniff my hand but if there isn't a treat he'll go back in his house. I let him out of his cage after about 5 days and let him run around for a bit. Now the first thing he wants to do whenever I open the cage is run out, I try to hold him but he just squirms in my hand and tries to get away. Is there anything I can do to get him to "unlearn" these behaviors and trust me more? and how do I get him to be less fussy when I try to hold him?
