Environment Canada estimates that cats kill an estimated 196 million birds in Canada each year, far more than all other human-linked bird kills combined. In comparison, office buildings only kill an estimated 64,000 birds die that way each year while houses kill 22.4 million birds a year. Power lines claim another 25.6 million, while vehicles kill 13.8 million.
While some people debate whether it’s permissible to let your cat go outdoors, indoor cats are safer and pose far less risk to others. If you have a cat, consider keeping it inside and get toys and other distractions to keep an indoor cat happy. The birds outside your window will thank you.
