Which are better ratters dogs or cats?

Cats, basically, are better at catching mice, rats, etc., than dogs because they are faster, more agile and can get into places many dogs would not fit. Plus, just as rodents have the ability to climb a variety of objects, cats are able also to climb whereas dogs are not usually climbers. Some dogs are definitely very good at catching rodents, but on the whole, cats do usually out shine their canine buddies.
