I know I don't have to explain to folks how destructive birds can be...whenever Muffin finds a hidey hole, I put lots of stuff in there like boxes and paper so he doesn't chew on the walls.
Muffin stripped the vinyl covering off the baseboards to bare wood. You can't buy this kind of trim anymore, so we'll have to get some pine. Last year I was on the ball about putting some wood around there, but instead of buying pine, my husband bought cedar because it's more durable. That's true, but apparently cedar can be toxic to birds, so that was a no go.
