...Last year I moved into an apartment that had an old bathtub in the back that served as a big ice bucket for beer, etc for BBQs. I converted its use into a summer bathing tub for annie. Now she can sun outside & I can simply drain & replace the water with a hose everyday without a whole filter contraption. The flowers from the overhead vines sometimes fall in the water, giving the tub a water-lily pond effect (I think!). Since Annie hibernates all winter (under the bathroom sink she's both water & air compatible), having her outside in the tub means that I no longer have to have a giant, smelly, expensive aquarium inside the apartment! EXTRA! Pet design you covet most or what would you buy for your pet if you had all the money in the world: I would definitely buy a place with a giant garden in the back & make a delightful lily pad-filled pond surrounded by sunning rocks & greenery for Annie.
