Me and my wife adopted a Japanese chin named batman from the shelter. We brought him home yesterday (Tuesday) evening. He was so calm last night and this morning that when I left for work at 11:30 I decided to not put him in the kennel and see how he did for the 5 hours he would be alone. I was extra careful to check and make sure all doors were tightly shut and locked. It's been getting pretty hot here lately so I left a window with a screen open. Batman somehow figured out that the screen wasn't perfectly secure and pushed till it bent open and got out. Less than a day after we got him.
I was totally freaking out, looking everywhere for him, while my wife called the shelter. Thankfully they have him. I feel like such a bad person. I guess it's "kennel up" everytime he's alone.
