Horace Nalle, a business leader in the animal vaccine industry, actively supports animal welfare causes through the Atlanta Humane Society, where he serves on the board of directors. One of Horace Nalle’s interests is the threat to endangered songbirds by feral cats.
According to research by the United States Fish and Wildlife Service and the Smithsonian Migratory Bird Center, cats kill up to 3.6 billion birds annually in America. The vast majority of these birds are killed by feral and stray cats. A study published in the Journal of Wildlife Diseases in June 2016 suggests that feral cats also endanger bird populations by acting as disease carriers.
One solution to the problem could be to target irresponsible cat owners who do not spay or neuter their pets and contribute to the feral and stray cat population. However, mandatory spay and neuter legislation is controversial and has little evidence to support its effectiveness.
