In many localities is it against the law to feed feral cats. You feed them, they are yours, you have to take them to the vet for shots, keep them indoors, etc. You must be a bird hater. If cats were raccoons we would find a way to control them. Cats are an invasive species and should be controlled or killed to save our environment. https://www.audubon.org/news/feral-cat-predation-birds-costs-billions-dollars-year

From Florida Fish and Wildlife:
Domestic cats can have impacts on native wildlife:
Domestic cats are not a part of Florida’s natural ecosystem. A single individual free-ranging cat may kill 100 or more birds and mammals per year. Scientists in Wisconsin estimate that cats kill at least 7.8 million birds per year in that state alone. Even cats with bells on their collars kill or injure birds and small mammals.
Cats compete with native wildlife and can spread disease. Outdoor cats have been identified as the primary host in the transmission of toxoplasmosis to wildlife, a disease which has caused death in manatees and other mammals.
Domestic cats can create a nuisance and cause damage, such as killing poultry.
Free-ranging cats can kill birds at bird feeders reducing opportunities for wildlife viewing.
Cats can be a nuisance in gardens when they defecate and cover their feces by digging.
