I don't know who created 'el gato secret story' as there's not enough information given. It could be an independent author or a small publishing house.
Since we don't have much information about 'el gato secret story', it could be a variety of things. It might be a children's story, in which case the secret could be something simple and innocent like the cat's favorite hiding spot in the garden. Or it could be a more complex story for an older audience, perhaps involving a mystery that the cat is trying to solve, or a secret that has to do with the cat's past or its family. It could also be a cultural story specific to a certain region where cats hold a particular significance and the secret is related to that cultural meaning.
I'm not entirely sure as I haven't read it. But perhaps it's about a black cat, 'el gato negro', which could be the central character. It might involve some kind of adventure or mystery that the cat gets into, typical of many graphic novels.
Searching on social media platforms might also yield some results. For example, on Twitter or Instagram, there could be fans or reviewers who have shared their opinions on the 'el gato negro graphic novel'. They might discuss things like how unique the concept is. If it has a dark or mysterious theme as the name 'el gato negro' (the black cat) might suggest, it could be a big draw for some readers, and reviewers would likely mention that aspect as well.
Well, it's hard to say for sure. You'd have to look into the background and the creator's statements to determine if it's based on actual events. Sometimes what seems like a true story could have a lot of creative liberties taken.
El Deafo is indeed a true story. The author drew inspiration from her own childhood and experiences with hearing loss to create the narrative. It offers an authentic and heartfelt account.
