My kid came home with these crazy looking pictures I'm not sure what's going on . He thinks rats or possum . Customer said its new and just happened . I said ground hog . He couldn't make out the tracks

What your looking at is under the kitchen sink and its open under the sink and there's a bath tub .there's a wall but open under the sink.I asked if its on a slab or is there a wooddeck .he dint no but said it was all sandy like .he said there's a deck outside but could see under it becase it was to low to the ground .I tell ya if it is rats I would run .can't be rats he would have seen dropings
