Imagine what a newly adopted dog or cat is thinking on the ride home from the animal shelter. Where am I going now? Who is this person? What's happening next?

There's likely some trepidation mixed with happiness and a whole lot of exhaustion after the noise and commotion they just left.

Here's a look at some of those sweet faces on the way to their new home or enjoying their first day with their new forever families.
