Best plants
A dim room and a curious pet is the toughest combination to plant for. These species clear both bars at once: ASPCA non-toxic to cats and dogs, and able to live without direct sun.
How this list is built: plants that are both ASPCA non-toxic to cats and dogs and need no direct sun (low or medium-indirect light)— filtered from Growli's structured plant-care library, not hand-picked, so it stays consistent and checkable.
