I would watch it again. I laughed throughout the movie and it was much better than I expected. Like one reviewer mentioned, it similar to Homeward Bound, but not. You have the talking animals and real life people.
I was told about the movie, because it had a Maine Coon cat in it. That got me to watch it. The silliness and the interactions between all the characters is what kept me watching it.
You have the cat who truly was a diva, evolved into a loveable kitty. The puppy, who stole my heart early on. Almost made me cry. The interactions between the two had a couple profound moments. I'm actually hoping for a sequel.
The humans involved, were interesting with some twists and surprises in the movie. Even the bad guys were enjoyable...sorta.
Very enjoyable movie.
