Nineteen years old

Scruffy, the cat, is nineteen years old. At the Vets' clinic there is a chart which allows us to translate a cat's age into a timeline on that of the average human life span. A simple way is to multiply the age by x (where x=7), which makes Scruffy  133years old. That can't be right. x cannot be a constant number and must vary. I have to pop into the clinic. This musing results from my noticing how smart she still is. This afternoon,taking advantage of the break in the weather, we were blocking wood. We took a breather and the cat, which has been housebound for quite a while, chose to come out with us. We went about our tasks out of her sight. In a little while she came to where we were and I walked her to the doors to let her in. Old cats cool fast in Canadian winters.
