I live with three cats and that has led me to think about things in a different way. My last post introduced the concept of cat math, whereby two cats minus one cat equals three cats.

Today, I have a new equation: 2C + C = 2p + 2f where C represents number of cats, p represents volume of deposits in the litter box, and f represents the amount of food consumed. One more cat in the house has doubled what we find in the litter box, as well as doubled bags of Iams purchased.

The results are counterintuitive, but that’s the nature of cat math. It represents a phenomenon not ever studied at MIT or the University of Chicago. Only a keen observer of the world around her would recognize and report on this quirk of nature. My husband once said that my brain rarely sits in idle for very long. I’ll bet Einstein’s wife said the same thing about him.
