So you want to have a story about pet Nearly Normal Animals or Partially Civilized Animals. You want them to go on adventures and run around without much issue. How can you do this if they're a pet? After all, pets have owners to come home to, if they're even allowed to leave their houses.
Simple: make them feral or stray animals (domesticated animals without human owners). note
They don't need elaborate excuses to leave their owners, it won't seem weird how you rarely mention their owner, and they can do whatever they please, unless the Diabolical Dog Catcher or some other antagonistic human comes along. You can even give feral animals their own societies, religions, and beliefs created due to their lack of human supervision.
This trope is a general staple of Xenofiction. It can be seen as the animal equivalent of Conveniently an Orphan. Sometimes the protagonist will go From Stray to Pet at the end, though it's even more common for the main characters to start as pets who became strays (instead of being born feral).
