I won't even mention boston fern cuz who's crazy enough to fight that? Not me.
You are smart to minimize the losses. Nobody likes having to strip the big healthy leaves before bringing inside (Plumeria too, etc) but even more , nobody likes picking them up off the floor inside.
A big cane begonia Sophie Cecile?is tossing a leaf here and there. But it's in 'maintenance mode' and drops them into its own pot.
I have a small leafed coleus in a pot it somehow hates, and that's dropping leaves. I'm not sure what happened. But young rooted pieces in their own small pot are behaving.
With a cat, I don't have a D marginata- he'd chew on it. But, yeah.
