I think pet is a best friend for human-beings. It has been a custom to possess a pet for long time. And they may be feel like family. But lots of neighbors may be feel uncomfortable because of their noisy NOISE, barking and even their masters are a burden for not cleaning their traces. I have raised the birds for 6 months. and there were no shining day that they are calm. They have such an troublesome to be tamed. And they also has HAVE a feeling to go out and talked with their friend. They have instinct to live in a nature environment for them is important.
