THIS CAT IS A BIOTIC LIMITING FACTOR. THE REASON SHE IS A BIOTIC FACTOR IS BECAUSE SHE IS LIVING. SHE KILLS AND EATS BUGS SUCH AS SPIDERS, BEES, FLIES, MOSQUITOES, AND OTHER INSECTS TO LIMIT OTHER ANIMALS FROM EATING THEM. SHE ALSO KILLS AND EATS BIRDS TO LIMIT THEM FOR OTHER ANIMALS TO EAT AND TO NOT ALLOW THEM TO GERMINATE SEEDS.
