Thank you Doni Eve for your informative letter (“Know the laws!” Oct.16, Sooke News Mirror) regarding the harm done from indiscriminate use of rat poison.
As well as those animals who initially ingest the poison there are other unintentional targets of rodenticides — raptors.
A Canadian Wildlife Services study addressed this issue at the fifth North American Ornithological Conference. All owls tested had evidence of rodenticides in their system and it was considered the cause of death.
Whether it is a poisoned rat or cat, etc., if they are then predated upon by owls, hawks, eagles the danger and mortality becomes magnified.
