Yes the basement is a great source of discovery for my cats. We have two fish tanks and in the past we have used artificial plastic plants in the tanks. Currently we have African cichlids (a whole nother story!) so don't use any plants at all. Anyway, for some reason my cat, Andy, keeps rooting around in the bag with the artificial plastic plants and constantly brings them upstairs. He has to go through a "flap" door and I would love to see him in the act, coming through the door with a plastic plant in his mouth! Can't imagine what the attraction is.....nails, pens, plants.....who knows?
