Coyotes should eat most of the feral cats that do not die on their own from injury and illness. Half of feral kittens are dead before the 12 month mark. Of those feral cats that survive to 1 year, the expected lifespan is 1 more year. Sure, a lot of songbirds, quail, nesting ducks, rabbits and squirrels will be killed by feral cats. The kindness intended by setting feral cats loose is not even that kind to the feral cats and certainly not to actual wildlife that is native to the area. The "no-kill" policy is a terrible name as the cats are doomed as are the wildlife they will kill. A better name would be "kill out of view" policy.
