There’s a movie I saw about 10 or so years ago starring a Dog (a pug I think) and a Cat (an orangish cute kitty).
They were outdoor animals (on a farm I think) and a voiceover (male) narrated the action.
I’d love to see it again, but I can’t recall the name, or the character’s names. The animals were protrayed as best friends and each had litters of achingly cute offspring in the end.
For some reason I think it’s Japanese film although the narrative I heard was in English.
