The Three Amigos

Bali, Tahoe, and Yuki are at a loss to explain what their Humans are doing as they move about the house holding onto each other as the push along a metal tubular contraption that is missing two of its four wheels.
No matter though, they can feel the love and the sunshine coming in the back door window is delicious.
Kathy is making excellent progress with the physical therapy exercises she is to do twice a day.
The pain medication is making life tolerable and she is reporting her new knees are moving "smoothly and freely".
Kathy is a marvel.
