Should I let my brother know that I’m a furry ? This is urgent. Read the caption

So, I borrowed my brother’s ipad for drawing furries. I was making artworks for souvenirs at a local upcoming con, (that I probably can’t really show yet) and I’m wondering if I should leave the last artwork in the ipad. Btw me and my brother don’t live together and he is 4 years younger than me (I’m 18). The only thing I heard from him about furries is him asking if they can enter a playground for dogs 🙄. I think he’s gonna find out eventually but idk if I want it now. He’s gonna take his ipad in 1-2 hour. (There is nothing nsfw on the ipad). I just don’t want to ruin our relationship if he doesn’t like furries. Sorry if I’m being stupid rn. I’m overthinking too much
