Seems like it's possible to miss out on the Catnip, meaning you can't unlock the scene with Rosie.
Also, you can get infinite Lemon Pies for some reason.
there’s an alternative way to get catnip, so it should always be possible to unlock Rosie.
There’s no limit on the lemon pies because you need them later on. We might change this later, but for now it shouldn’t matter much.
