So far the new foldable pool ('buddy and belle' brand, made in China) is a great success. I had put it away, and it folded up really small, and fairly easily, though of course I couldn't' get it back into the original box. Who ever can?
It fitted comfortably into an ordinary cotton shopping bag, 42 cm square (about 17 inches).
Today it's hot and the house is full of workmen replacing a damaged ceiling, so there's no cooling possible. It seemed like a good time to try the pool once again.
Penny doesn't do much jumping these days, due to a past operation on her left knee and to a degree of arthritis, but she leapt in and out today, having fun. We'll hope she doesn't pay the price tomorrow.
