niu niu(can pronounce new new) is much more open than his brother orange, but since they both were stay cat, so he is also very easy to get scared, but he is a little bit more brave than orange is that, they always looking for me or my husband once he wake up, but if he hears door bell he will just hide, but he is totally fine with hide, and he love food, so he is kinda a bit bigger than orange, you can just let him be if we could have you visit our house
