When pets run away

I had multiple pets escaped during my childhood.

A turtle, and two Parakeet.

I had that turtle since I was six. One day it was just gone and I couldn't find it at all. I thought someone in the neighborhood could have found it and took it in. As for the parakeets, they broke the cage and flew away. We realized that in the morning and there was nothing we could do. There was no sign of them anywhere.

There were also two Parakeets flew into my home a few years later on two separated occasions. I took them in lol. There was no way to know where they came from, and since they couldn't have survived on their own, I took them in and gave them food.
