Are cats r-selected species?
Cats and dogs are r-selected compared to humans, but K-selected compared to mice and rats. Mice and rats, in turn, are K-selected compared to most insects. We can think of an r-K selection continuum and an organism’s position along it in a particular environment at a given instant in time (Pianka 1970).
