You can see these Pokémon you've never caught as if they're yours, right there in the Dex. Shiny Galarian Meowth is currently unreleased but viewable in Pokémon GO. Credit: Niantic ...

Galarian Meowth is similar to the non-Paldean Wooper in that, while it’s available for players to collect in Pokemon Scarlet and Violet, it actually isn’t part of the game’s Pokedex.

Classified as a very common spawn, rest assured you won’t have to spend much time to catch Meowth in Pokémon Scarlet and Violet.
