Same cat : rat ratio, so the same amount of time. 3 minutes.
3 minutes, one rat per cat per three minutes was established as the rule of thumb, or paw as it were, in the example
Why do you care?
Googled it.....3 minutes
Unless this happened in East Timor of Southeast Asia where just a couple thousand years ago, the world's largest rat, weighing more than the average house cat, was found. Then it would become a rat race.......get it? rat race....LMBO X-)
