It depends where you live. Rats are less common outside the city. There are plenty of field mice and of course still some rats but they generally all stay outside as long as you've kept up with house maintenance. We've had a few rats get into equipment outside our house over the years and probably a few (or squirrels) in the attic but to this date we've yet to see any evidence of one inside the house itself or anywhere the cats could get to them.
