Anyone know what's causing this?
We noticed a tiny hole forming on the drywall here, but all of a sudden it became this huge thing. We're about to move so we need to fix it, but we're perplexed as to what could have caused it.
We have a toddler who we have never seen lick the walls, but we also have 2 cats, one's barely a year old. We haven't noticed the cats lick the wall either, but maybe they're doing it at night?
Any help is appreciated on both fixing and solving this problem. Thank you.
