Had the chinchilla for just over a year now, not had any problems. They're nocturnal so he's usually only awake in the evenings/mornings, in that picture i'd just woken him up, he looks half asleep hehe. He likes running about the house when I let him out, the dog doesn't seem to want to do anything besides sniffing him, and the cat doesn't bother lol, it's too lazy. Oh yeah, he loves being tickled behind his ears and on his belly too.
