Since 1944, North Shore Animal League America has been saving the lives of innocent dogs, cats, puppies, and kittens — over 1,000,000 to date. We have saved a million lives. Help us save a million more. The Animal League is the world's largest no-kill animal rescue and adoption organization. Our mission is to carry out our hands-on rescue, rehabilitation and adoption efforts to save the lives of as many companion animals as possible. The Animal League exists to promote education to increase shelter adoptions, reduce animal cruelty and advance the highest standards in animal welfare. Also to provide high-quality veterinary care to our Long Island community.
