Best plants
A hanging plant is meant to be out of reach — but pets climb, and leaves drop. These trailing and climbing species clear both bars: a cascading habit and ASPCA non-toxic status for cats and dogs.
How this list is built: plants with a trailing, vining, or climbing habit that are also ASPCA non-toxic to cats and dogs— filtered from Growli's structured plant-care library, not hand-picked, so it stays consistent and checkable.
