I agree with what everyone has said. I don't think chins should be given as Christmas/birthday gifts UNLESS the person has done their research and understand what goes into a chinchilla's care. It's a huge responsibility, as all pets are. I never recommend a parent buy a chinchilla for their child. If the parent is willing to take care of the animal after the child loses interest, maybe. Chinchillas are different creatures, they are not kid friendly in my opinion. They are more an adult's pet. Someone that has patience and understanding.
Chichi was a 5 year old's pet before I got her. She's always been the nervous type. She's very skittish and I don't ever think she will change from that. I'm not sure if being the child's pet scared her and now she doesn't trust? When I went to pick her up, I could tell she was grabbed/handled and she did not enjoy it. That's just how kids are. They want to grab at everything and I don't know if younger kids understand how fragile chinchillas are...
