The Drinkwell® Aqua Garden is a Hydroponic Cat Grass Garden designed to work specifically with the Original Drinkwell® Pet Fountain and the Drinkwell® Platinum Pet Fountain (with the use of the Aqua Garden adapter, included with the Platinum Fountain). Fountains are sold separately. The constant circulation of water causes the 100% organic wheat grass seeds to germinate and begin to grow within a few days, with full growth at around seven or eight days. The grass treat becomes available to the pet as soon as it begins to grow out of the seed pod. The Aqua Garden includes one seed pod and one basket. Replaceable seed pods are also available to grow again and again! Garden only! Does not include fountain.
