They are adorable in the wild where they belong. People need to do a lot of research before they go out and buy an animal. The shelters are full of dogs and cats because humans don't bother to find out everything they need to know about the breed they purchased. And that's just dogs and cats. The moment a child or an adult gets injured because they don't know how to properly handle their captive pet the animal is the one who suffers or is killed. Those quills can hurt if the animal feels threatened.
I had a pet sitting client that bragged to me about how her husband rough housed with their newly adopted BIG dog. I told her that wasn't a good idea because it only teaches the dog to be aggressive. I suggested her hubby find a better way to bond with the dog like throwing a ball or something. She ignored me. The dog bit the husband, the dog was killed.
