Have you read Charles Dodgson (a.k.a. Lewis Carroll) on the
question
of how many cats it takes to kill rats in a given time?

No, but I look forward to hearing where he wrote that.

"The Monthly Packet", February 1880. It is on pages 140-142 of
The Magic of Lewis Carrol by John Fisher (Penguin), but my copy
was published in 1975.

If all the animals are reasonably spaced, I guess the number killed
per unit time is proportional to the product of the number of cats
and
rats.

You've got to the first step.

I'll have to hunt the net for a copy of the book.
