I don't think so. While there could be some fanfictions that involve pets in the Harry Potter world, it's not a very common type. Most popular Harry Potter fanfictions tend to revolve around the main plotlines of the original series like the Triwizard Tournament, the fight against the Death Eaters, or the secrets of Hogwarts. Pets are often just secondary elements in the original stories, so it's less likely for a whole fanfiction to be centered around them.
It's not common. The Harry Potter series has so many rich elements such as the complex magic system, the dark and light side of wizardry, and the character development of Harry and his friends. Fanfiction writers usually explore these areas more deeply. While pets are a part of the series, they are not as central as other aspects. So a fanfiction that is solely about Harry Potter and pets is not as common as those that deal with broader themes of the wizarding world.
