Childproofing litterbox?

Ashleigh 🐱
My son is only three months old, so I know that I have a little while before I need to worry, but I'm trying to childproof our apartment and the one area I'm concerned about is the litterbox. Even with cleaning the area frequently, I foresee it being an issue once my little guy is more mobile. I live in a small apartment and there is no area that I can gate off to prevent him from having access to it. Of course, I plan to supervise him constantly but I was just curious if anyone has any tips for me!
