The story has a sad ending.
Late Sunday afternoon, I felt well enough to take the poor things for a shorter walk along the pipeline. I let them in through the back door and the little one was so excited by this time that she slipped on the polished floor, hyperextended one of its back legs, and ruptured the anterior cruciate ligament.
(If it will make you feel better, I will send you the bill.
